Color Temperature

Kelvin temperature describes the color appearance of light sources from warm (orange) to cool (blue).

Creating Kelvin Colors

const tint = @import("tint");

// Warm light (candle, incandescent)
const warm = tint.kelvin(2700);

// Daylight
const daylight = tint.kelvin(6500);

// Cool blue sky
const cool = tint.kelvin(10000);

Common Temperatures

Kelvin	Description
1000K	Candle light
2000K	Warm white
2700K	Incandescent
3000K	Halogen
4000K	Fluorescent
5000K	Direct sunlight
6500K	Cloudy daylight
8000K	Light blue sky
10000K	Blue sky
20000K	Deep blue sky

Temperature to RGB

const rgb = tint.Color.temperatureToRgb(6500);
std.debug.print("RGB: ({d},{d},{d})\n", .{ rgb.r, rgb.g, rgb.b });
