Step-by-step math

Every number below is computed from the input, nothing is looked up.

1. input
```
oklch(0.64713 0.21733 36.851)
```

2. OKLCH → Oklab

a = C·cos H = 0.17391
b = C·sin H = 0.13034

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.744184
m′ = L − 0.1056·a − 0.0639·b = 0.620449
s′ = L − 0.0895·a − 1.2915·b = 0.463235

4. cube

l = 0.744184³ = 0.412136
m = 0.620449³ = 0.238847
s = 0.463235³ = 0.099404

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.913097
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.066634
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.000005

6. linear → sRGB, × 255

R = 0.96078 × 255 = 245.00 → 245
G = 0.28629 × 255 = 73.00 → 73
B = 0.00007 × 255 = 0.02 → 0

7. RGB → HEX
```
#F54900
```
