Table of red, green, blue, and alpha float values between 0 and 1. All values are optional, default optional value for colors is 0, for alpha 1. Alternatively, values can be from 0-255, they are interpreted as such if at least one value is > 1.
Color allows the short-hand notation of passing an array of exactly 3 or 4 numbers.
The game usually expects colors to be in pre-multiplied form (color channels are pre-multiplied by alpha).
| name | meaning | type |
|---|---|---|
| r | [optional, default 0] red value | float |
| g | [optional, default 0] green value | float |
| b | [optional, default 0] blue value | float |
| a | [optional, default 1] alpha value - transparency | float |
Examples
color = {r=1, g=0, b=0, a=0.5} -- red
color = {r=1, a=0.5} -- the same red, omitting 0 colors
color = {1, 0, 0, 0.5} -- also the same red
color = {0, 0, 1} -- blue
color = {} -- black
