Color converter
HEX to GLSL and GLSL to HEX
Type a HEX value or a GLSL value, and the other one appears as you type. Every other notation of the same color is listed below, with each step of the maths.
The converter needs JavaScript. The values shown are for #D3AF37, and the worked examples below read without it.

Every step of the maths
How HEX becomes GLSL
Each step shows the values for the color above, as the converter computes them.
- Start Hex digits
#D3AF37 - Back 8-bit channels
each pair of digits read as a byte211 175 55 - Back sRGB channels, 0 to 1
each byte ÷ 2550.8275 0.6863 0.2157 - Then GLSL
the 0 to 1 values as a vectorvec3(0.8275, 0.6863, 0.2157)
GLSL
About GLSL
Shaders take colors as vectors of floats from 0 to 1: vec3 for red, green and blue, vec4 with alpha. These are the sRGB-encoded values; a renderer that works in linear light needs the linear sRGB values instead.
How this page writes it
- Four decimal places, and every number has a decimal point, as GLSL needs for floats.
Watch for
- Lighting maths on encoded sRGB comes out too dark in the mid-tones; convert to linear first.
Worked examples
HEX to GLSL
Each row is the converter's own output, and a test re-runs every row.
| Color | HEX | GLSL |
|---|---|---|
| White | #FFFFFF | vec3(1.0, 1.0, 1.0) |
| Black | #000000 | vec3(0.0, 0.0, 0.0) |
| Middle gray | #808080 | vec3(0.502, 0.502, 0.502) |
| Red | #FF0000 | vec3(1.0, 0.0, 0.0) |
| Green | #00FF00 | vec3(0.0, 1.0, 0.0) |
| Blue | #0000FF | vec3(0.0, 0.0, 1.0) |
| Royal blue | #2563EB | vec3(0.1451, 0.3882, 0.9216) |
| Gold | #D3AF37 | vec3(0.8275, 0.6863, 0.2157) |

- An automated test recomputes every value on this page and reads every format back.
- Checked with a keyboard, the axe engine and Playwright in Chromium, in light and dark themes at phone and desktop widths. It has not yet been checked with a screen reader.
