Step-by-step math

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

1. input
```
oklch(0.39353 0.02271 107.399)
```

2. OKLCH → Oklab

a = C·cos H = -0.00679
b = C·sin H = 0.02167

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.395515
m′ = L − 0.1056·a − 0.0639·b = 0.392863
s′ = L − 0.0895·a − 1.2915·b = 0.366150

4. cube

l = 0.395515³ = 0.061871
m = 0.392863³ = 0.060635
s = 0.366150³ = 0.049088

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.063008
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.063008
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.040912

6. linear → sRGB, × 255

R = 0.27843 × 255 = 71.00 → 71
G = 0.27843 × 255 = 71.00 → 71
B = 0.22352 × 255 = 57.00 → 57

7. RGB → HEX
```
