usage: require("colors")
for the most part, this is a library containing color codes from paint tool
It also contains functions for working with color

smcolor consts:

methods:

• colors.hsvToRgb(h, s, v):r,g,b - all arguments have a range from 0 to 1, the output values also have a range from 0 to 1
• colors.hsvToRgb256(h, s, v):r,g,b - all arguments have a range from 0 to 255, the output values also have a range from 0 to 255 (It works faster)
• colors.pack(r:number, g:number, b:number):color - converts rgb (from 0 to 255) to 0xRRGGBB
• colors.unpack(color):r,g,b - converts 0xRRGGBB to rgb (from 0 to 255)
• colors.packFloat(r:number, g:number, b:number):color - converts rgb (from 0 to 1) to 0xRRGGBB
• colors.unpackFloat(color):r,g,b - converts 0xRRGGBB to rgb (from 0 to 1)
• colors.formatToNumber(color):number - converts color from any format to 0xRRGGBB
• colors.formatToColor(color):number - converts color from any format to smcolor object
• colors.formatToString(color):number - converts color from any format to "RRGGBB"
• colors.combineColorToNumber(value:0-1, anycolor, anycolor):number - makes a color gradient (output 0xRRGGBB)
• colors.combineColorToColor(value:0-1, anycolor, anycolor):number - makes a color gradient (output smcolor)
• colors.combineColorToString(value:0-1, anycolor, anycolor):number - makes a color gradient (output "RRGGBB")

fills the screen with a solid color from the paint tool

                local colors = require("colors")
local display = getComponent("display")

display.clear(colors.str.Red[2]) --fill the screen with red painttool
display.forceFlush()

function callback_loop()
    if _endtick then
        display.clear()
        display.forceFlush()
    end
end
            

makes the screen shimmer

                local colors = require("colors")
local display = getComponent("display")

function callback_loop()
    if _endtick then
        display.clear()
        display.forceFlush()
        return
    end

    display.clear(colors.pack(colors.hsvToRgb256(getUptime() % 256, 255, 255)))
    display.flush()
end
            

format color

                local colors = require("colors")

local function result(title, val)
    print(title, type(val), val)
end

result("formatToNumber(number)", colors.formatToNumber(0x663399))

result("formatToString(color)", colors.formatToString(sm.color.new(0x663399ff)))

function callback_loop() end
            

the color gradient

                local colors = require("colors")
local display = getComponent("display")

local color1, color2 = 0xff0000, 0xff00ff
local width = display.getWidth()
local maxWidth = width - 1

for ix = 0, maxWidth do
    display.fillRect(ix, 0, 1, display.getHeight(), colors.combineColorToNumber(ix / maxWidth, color1, color2))
end
display.flush()

function callback_loop() end
