--[[
Bicolor module to contain colors for Module:Bicolor

We can load this efficiently with
local c = mw.loadData("Module:Bicolor/data")
local colors = c.colors
local colorvalues = c.colorvalues
local colortitles = c.colortitles

Creating the definitions like this offers us tables indexed by number or by color name
and combinations as a sequence or an indexed set for efficient testing

-- color definitions as a sequence of pairs of values
-- will be used as colors[n].name and colors[n].value
-- insert new colors here, preferably in alphabetical order
