This is a pretty extensive dyes mod, which has the sole purpose of supplying a
complete set of colors and a few greys, all of which are intended to be used by
other mods as needed to make colored objects. It uses Ironzorg's Flowers mod
as the source of the actual pigments. Flowers can be had from one of the links
below, or as part of neko259's Nature Pack.
as the source of the actual pigments, which can be had from one of the links
below.
In total, this mod provides 89 colors and greys.
Dependencies: flowers
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. The modding template at the bottom of
this post, while intended to render the entire palette, is still just a
template - please trim out the colors and shades you don't actually need.
Dependencies: Nature Pack OR flowers
Recommends: buckets, junglegrass

The Palette:
[ https://github.com/VanessaE/unifieddyes/raw/master/color-swatches.png ]
[ The complete official palette, showing all 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.
Usage instructions, technical information
=========================================
Colors
Getting Started
---------------
Creating a particular color of dye is pretty simple - just harvest coal,
cactus, or the appropriate flowers and start smelting them and crafting the
results together to get the various colors. There are 12 base colors, which
are formed as follows (the degree figure is that color's hue on a standard HSV
color wheel, and is what is used in the textures supplied with this mod):
First thing's first: you're going to need something in which to contain your
dyes - namely, glass bottles. Making them is very simple: Smelt some sand or
desert sand into glass blocks as usual, then put one glass block back into the
furnace to smelt it into a 9-pack of glass bottles.
Red (0°): smelt one rose (yields 2 portions of red dye)
Orange (30°): smelt one tulip (yields 2) or mix red+yellow (yields 2)
Yellow (60°): smelt one yellow dandelion (yields 2)
Lime (90°): mix yellow + green (yields 2)
Green (120°): smelt one cactus or one waterlily (yields 2), or mix
yellow + blue (yields 2)
Aqua (150°): mix green + cyan (yields 2)
Cyan (180°): green + blue (yields 2)
Sky blue (210°): mix cyan + blue (yields 2)
Blue (240°): Smelt one viola (yields 2)
Violet (270°): mix blue + magenta (yields 2) or mix
2 blues + 1 red (yields 3)
Magenta (300°): Mix blue + red (yields 2)
Red-violet (330°): mix magenta + red (yields 2)
[ https://github.com/VanessaE/unifieddyes/raw/master/bottle-9-pack.png ]
Now, let's fill them up with some dye base. Take one 9-pack of bottles and
craft it with one piece of jungle grass and one bucket of water. The result
will be nine individual bottles of uncolored dye base and an empty bucket.
Greys
-----
[ https://github.com/VanessaE/unifieddyes/raw/master/dye-base.png ]
There are also three shades of grey plus pure black and pure white (figures in
parenthesis indicate the intended brightness of the shade, relative to white):
Next, we need to harvest some materials to make the pigments themselves from.
For this, you need one or more of the following: roses (red), tulips (orange),
dandelions (yellow), cactus or waterlilies (green), violas (blue), coal
("carbon black"), or stone+junglegrass+water (white, "titanium dioxide").
Simply wander around your world and collect whichever of the above you need to
get your colors.
Black (0%): smelt one piece of coal (yields 2)
Dark grey (25%): mix one portion of white paint with two portions of black
dye (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 (100%): See below.
Once that's done, simply smelt a flower, coal, or stone to get the associated
pigment. One flower or lump of coal yields 2 portions of pigment powder,
cactus yields 6, while stone yields 10 (of titanium dioxide).
Now that you have your pigments, take one bottle of the dye base you made above
and craft it with one portion of a pigment to get a usable bottle of dye of
that color.
White Paint
-----------
[ https://github.com/VanessaE/unifieddyes/raw/master/craft-red-dye.png ]
To get the white paint mentioned above, first smelt some cobble into smooth
stone as usual. Then, smelt one smooth stone block to get 10 portions of
Titanium Dioxide. Finally, craft one portion of that with a bucket of water
and one piece of jungle grass. Yields one bucket of white paint.
When all is said and done, the above ingredients and process can be repeated
for all 7 of these "root" colors, resulting in...

Orange, Yellow, Green, Blue, White, and Black.

All colors are fashioned using mixtures of the 'root' colors created above.

[ The 12 "full" colors and the five grey shades. ]
These 17 colors and greys can be formed using these recipes:
* Red (0°): smelt one rose (yields 2 portions of red dye)
* Orange (30°): smelt one tulip (yields 2) or mix red+yellow (yields 2)
* Yellow (60°): smelt one yellow dandelion (yields 2)
* Lime (90°): mix yellow + green (yields 2)
* Green (120°): smelt one cactus or one waterlily (yields 2),
or mix yellow + blue (yields 2)
* Aqua (150°): mix green + cyan (yields 2)
* Cyan (180°): green + blue (yields 2)
* Sky blue (210°): mix cyan + blue (yields 2)
* Blue (240°): Smelt one viola (yields 2)
* Violet (270°): mix blue + magenta (yields 2)
or mix 2 blues + 1 red (yields 3)
* Magenta (300°): Mix blue + red (yields 2)
* Red-violet (330°): mix magenta + red (yields 2)
* Black (7.5%): smelt one piece of coal (yields 2) -- Note that this dye is
only used with other dyes, not with the paints.
* Dark grey (25%): mix one portion of white paint with two portions of
carbon black powder (not the above black dye) (yields 3)
* Medium grey (50%): mix one white and one carbon black (yields 2)
* Light grey (75%): Mix two white and one carbon black (yields 3)
* White (95%): Craft one piece of jungle grass with one bucket of
water and one portion of titanium dioxide (yields 1).
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% relative to the 'full' version) version of a given color,
use two portions of black dye along with the base color, which yields three
portions of the final color.
To obtain a dark (33%) version of a given color, use two portions of black dye

To obtain a medium-brightness (66%) version of a given color, mix the desired
base color from the list above with one portion of black dye (for example,
medium lime = lime + black). All such mixtures yield two portions of the final
color.
To obtain the light (150%) version of a color, mix one portion of the
desired base color with one portion of white paint, which yields 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 paint. Yields 2 portions of the final

Low-saturation colors

while bright, full-saturation red would simply be "unifieddyes:red".
For example, low saturation dark yellow is "unifieddyes:dark_yellow_s50", while
bright, full-saturation red is simply "unifieddyes:red". For the greys, the
names are unifieddyes:white_paint, unifieddyes:lightgrey_paint,
unifieddyes:grey_paint, unifieddyes:darkgrey_paint, or unifieddyes:black.
See the texture filenames in the textures/ folder for further hints - all of
the item names follow the same format as the filenames, save for having a colon
(:) instead of the first underscore (_).
Mods should use the replacements= parameter in their crafting recipes, to
return the empty bottles and buckets after they've been used. Something like
this should do in the case of a bottle of dye:
replacements = { { 'unifieddyes:some_color_here', 'unifieddyes:empty_bottle' },
},
Empty bottles can be crafted back into 9-pack sets, which can then be recycled
into glass blocks by smelting them.
