Ok I figured it out.
local function rgb(r, g, b)
return r * 256 * 256 + g * 256 + b
end
from lua-fenster.
This library uses 24-bit colors. If you ever used hexadecimal colors in CSS or a graphics program like Photoshop, they work pretty similarly.
For example #ff0000
(Red) would look like 0xff0000
in Lua, which is just the number 16711680
in a nicer format.
So basically the colors go from 0x000000
(Black, 0
) to 0xffffff
(White, 16777215
).
Just play around with the window:set()
function and try different colors, I'm sure you'll figure it out.
For using RGB there is a utility called fenster.rgb()
which you can use to convert from and to RGB:
-- RGB to 24-bit color
fenster.rgb(255, 0, 0) -- returns 0xff0000
-- 24-bit color to RGB
fenster.rgb(0xff0000) -- returns 255, 0, 0

Similar to #8 I will turn this into a discussion as well in case someone has a similar question in the future.
