Colors

Colors in Pix are specified as hexadecimal literals or as references to named colors defined in a color block.

Hex colors

A hex color starts with # followed by 3, 6, or 8 hexadecimal digits. The digits are case-insensitive.

3-digit format

Each digit is expanded by repeating it. #E40 becomes #EE4400. Alpha defaults to fully opaque. 

#E40   // orange
#FFF   // white
#000   // black

6-digit format

Standard RGB hex: #RRGGBB. Each pair represents red, green, or blue in the range 0 to 255. Alpha defaults to fully opaque. 

#e84a00   // accent orange
#e8ddd0   // warm beige
#2a1208   // dark brown
#b0a090   // muted tan

8-digit format

RGB with alpha: #RRGGBBAA. The last two digits set opacity. FF is fully opaque, 00 is fully transparent. 

#e84a0080   // orange at 50% opacity
#e8ddd040   // beige at 25% opacity
#FFFFFF00   // fully transparent white

Color block

A color block defines named colors that can be reused throughout the program. Each entry maps a name to a hex color. 

color {
    warm: #e84a00
    light: #e8ddd0
    dark: #2a1208
}

Referencing named colors

Use color <name> wherever a color value is expected. 

draw x = 3 and y = 5 with color warm
pixel (10, 10) with color dark
circle (8, 8) radius 4 with color light
