Since the default dyes mod that +is supplied with Minetest "common" is now usable (via flowers, also included in +"common"), this mod has become more of an extension pack. + +Unified Dyes expands the standard dye set from 15 to 90 colors. + +IMPORTANT: This mod is not intended to suggest that you should use the entire +palette. Rather, I was hoping people would just choose maybe the dozen or so +most useful colors to use in their mods. + +Dependencies: default and dye from Minetest "common". This mod will NOT work +without these. This mod will NOT work without these. The default dye mod is +normally activated only in the standard "build" and "minetest_game" games, or perhaps if +someone has a modpack or game that includes them. + +Recommends: flowers from common. + +License: GPL 2.0 or above + +Install: Unzip the distribution file, rename the resultant +VanessaE-unifieddyes-blahblah folder to just "unifieddyes", and move it into +Minetest's mods folder. + +The Palette: + +[ http://digitalaudioconcepts.com/vanessa/hobbies/minetest/screenshots/color-swatches.png ] +[ The official palette, showing 84 colors and 5 greys. ] + +In the image above, the "50%" markings on the left next to each shade mean 50% +saturation for all hues in that shade line. Note that the "light" shades don't +have (or need) that variant. For the greys, the percentages shown are of +brightness relative to pure white. There are three special cases: Light red +has been aliased to default pink dye, and dark green has been aliased to +default dark greey dye. Brown dye also exists in the default set, it's just +not shown in the palette above. + + +Usage instructions, technical information +========================================= + +Getting Started +--------------- + +First thing's first: you're going to need to harvest some materials to make the +dyes from. For this, you need one or more of the following: roses (red), +tulips (orange), yellow dandelions (yellow), cactus (green), geraniums (blue), +violas (purple), coal (black), or white dandelions (white). Simply wander +around your world and collect whichever of the above you need to get your +colors. + +[ http://digitalaudioconcepts.com/vanessa/hobbies/minetest/screenshots/unifieddyes1.png ] +[ The 8 base colors directly obtainable from a material in the world. ] + +Simply place one of the above materials into the crafting grid to obtain four +portions of dye in that color From those initial 8 colors, you can directly +fashion another 11, for a total of 19 standard colors (including the various +greys): + +[ http://digitalaudioconcepts.com/vanessa/hobbies/minetest/screenshots/unifieddyes2.png ] +[ The complete 19-color standard set. ] + +The standardized colors and their crafting methods are as follows: + +* Red (0°): one rose +* Orange (30°): one tulip, or put one red dye and one yellow dye into the + crafting grid to mix them (yields 2) +* Yellow (60°): one yellow dandelion +* Lime (90°): mix yellow + green (yields 2) +* Green (120°): one cactus, or mix yellow + blue (yields 2) +* Aqua (150°): mix green + cyan (yields 2) +* Cyan (180°): mix green + blue (yields 2) +* Sky blue (210°): mix cyan + blue (yields 2) +* Blue (240°): one geranium +* Violet (270°): one viola, or mix blue + magenta (yields 2). +* Magenta (300°): mix blue + red (yields 2) +* Red-violet (330°): mix magenta + red (yields 2) + +* Black (7.5%): one piece of coal +* Dark grey (25%): mix one white + two black (yields 3) +* Medium grey (50%): mix one white and one black (yields 2) +* Light grey (75%): Mix two white and one black (yields 3) +* White (95%): one white dandelion. + +The degree figures are the colors' hues on a standard HSV color wheel, and are +what I used in the textures supplied with this mod. For the greys, the figures +in parenthesis indicate the intended brightness of the shade, relative to +white. Note that black and white don't go all the way to the bottom/top of the +scale, as doing so may crush some details in textures made in those shades (see +below, regarding semi-automatic texture generation). + + +Darker/Lighter colors +--------------------- + +To obtain a dark (33%) version of a given color, use two portions of black dye +along with the base color from the list above, which yields three portions of +the final color. + +To obtain a medium-brightness (66%) version of a given color, mix one portion +the base color with one portion of black dye (for example, medium lime = lime + +black). All such mixtures yield two portions of the final color. + +To obtain a light (150% over full) version of a given color, mix one portion of +the base color with one portion of white dye. Yields 2 portions of the final +color. + + +Low-saturation colors +--------------------- + +To get the low saturation (50%) version of one of the base colors, mix one or +more of white, black, or a shade of grey with the desired base color: + +Dark, low saturation: dark grey dye + color (yields 2), or two blacks + 1 white ++ color (yields 4). For example, dark, low-saturation red = red + dark grey, +or red + two black + one white. + +Medium brightness, low saturation: medium grey dye + color (yields 2), or black ++ white + color (yields 3). For example, medium, low-saturation green = green ++ medium grey, or green + black + white. + +Full, low saturation: light grey dye + color (yields 2), or 1 black + 2 whites ++ color (yields 4). For example, bright, low-saturation blue = blue + light +grey, or blue + black + 2 white. + +There is no low-saturation version of the "light" colors. + +Red + white always returns default pink dye, and black + green always returns +default dark green dye. + + +RGB values +---------- + +All RGB values and filenames for all colors and shades of grey are represented +in the file "colors.txt" (which was generated with the bash script +"listcolors.sh"), included in the distribution directory. Note that +listcolors.sh is an example only and was written for a different set of +textures than what Unified Dyes includes now. + + +Misc. Notes +----------- + +If you need to use /give commands, the item names for the standard set of 12 +regular "full" colors (plus pink, brown, and dark green) is simply "dye:color", +e.g. "dye:red", "dye:pink", or "dye:skyblue". Greys have a similar naming +convention: dye:white, dye:light_grey, dye:grey, dye:dark_grey, or dye:black. + +For everything beyond those initial 19 colors, the item names are of the +following format: + +unifieddyes:{"light_" or "medium_" or "dark_"}{color}{nothing or "_s50"}. + +For example, low saturation dark yellow is "unifieddyes:dark_yellow_s50", while +light normal-saturation red-violet would be "unifieddyes:light_redviolet". + +See the texture filenames in the textures/ folder for further hints - all of +the item names follow the same format as the corresponding filenames, save for +having a colon (:) instead of the first underscore (_). + + +Semi-automatic generation of textures +===================================== + +The texture generator script +---------------------------- + +Obviously, in order for this mod or the above template to be useful, you'll +need textures. If you plan to support the entire range of colors offered by +Unified Dyes, there is a BASH script included with this mod as well with the +above template named gentextures.sh, which will, with an appropriately- colored +and appropriately-named source texture, and possibly an overlay texture, +generate a complete set of colored and greyscale textures. + +The script requires bc (the calculator program) to handle some basic math +regarding the hue adjustments, and Imagemagick's "convert" program handles all +of the actual conversions. + +First thing's first though - you need source textures. Using your favorite +image editor, create a single version of your desired texture. Draw it in the +brightest, deepest shade of RED you can muster without losing any detail, and +save it out. Ideally, you will want the average color of the texture, when +taking into account all bright and dark areas, to be as close as possible to +the hex value #FF0000 (0 degrees, 100% saturation, pure red) without losing any +appreciable #detail. + +Save this source texture out as a PNG image, with a filename of +"whatever_base.png", where "whatever" is the one-word name of your mod - for +example, mymod_base.png. + +If you want to add an image on top of the colored blocks, such as a frame, +which you want to be the same color throughout all of the textures, create it +now. It should consist only of those parts of the textures that you want to +leave unchanged, with some level of alpha transparency everywhere else, +depending on how much of the image needs to remain unchanged. Save it out as a +PNG image, using any filename you want, for example myoverlay.png. + +Now, use chmod to make the script executable, if necessary, and run it. + +If you don't need the overlay, you just need to supply one command line +argument: the base name of your mod. The script will use that parameter as the +basis of its texture filenames. For example: + +./gentextures.sh mymod + +The script will then look for mymod_base.png and copy and convert it into +things like mymod_red.png, mymod_dark_blue.png, and so on. + +If you want to use an overlay also, skip the above step and run the script with +the base name as the first parameter, and the complete filename of your overlay +as the second instead. For example: + +./gentextures.sh mymod myoverlay.png + +Otherwise, the program will iterate through all of the hues and shades that are +supported by unifieddyes (though this is done manually, not by reading anything +from the mod), compositing your overlay image in after the recolor step, if +you're using that option. + +All of the output files will be placed in a new folder, generated-textures/ in +the current directory. Note that the script looks for the above files in the +current directory also. + +The script has a third mode as well: + +./gentextures.sh -t mymod myoverlay.png + +In this mode, the script will leave the base texture mymod_base.png unchanged, +and instead will rotate the colors of the overlay image and then composite that +onto the base texture. The same color changes will happen with the overlay in +this mode, so it's a good idea to make the overlay some fairly saturated shade +of red. Along with that, the base image should be some neutral color; any +color is fine as long as the result is what you wanted. + +The program attempts to verify that the files you've asked it to use will +actually work, and will exit immediately if the any are invalid, missing, etc. + +Use your favorite image browser or file manager to review the results in +generated-textures/, and if they're right, copy them over to the textures/ +folder in your mod. + +Note that this script does not generate brown and pink variations of your base +texture - you'll have to do those two manually. -- cgit v1.2.3
