Step-by-step math

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

1. input
```
oklch(0.46634 0.02493 107.329)
```

2. OKLCH → Oklab

a = C·cos H = -0.00743
b = C·sin H = 0.02380

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.468533
m′ = L − 0.1056·a − 0.0639·b = 0.465604
s′ = L − 0.0895·a − 1.2915·b = 0.436269

4. cube

l = 0.468533³ = 0.102854
m = 0.465604³ = 0.100937
s = 0.436269³ = 0.083035

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.104616
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.104616
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.070360

6. linear → sRGB, × 255

R = 0.35686 × 255 = 91.00 → 91
G = 0.35686 × 255 = 91.00 → 91
B = 0.29412 × 255 = 75.00 → 75

7. RGB → HEX
```
#5B5B4B
