Step-by-step math

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

1. input
```
oklch(0.36380 0.02934 323.885)
```

2. OKLCH → Oklab

a = C·cos H = 0.02370
b = C·sin H = -0.01729

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.369462
m′ = L − 0.1056·a − 0.0639·b = 0.362402
s′ = L − 0.0895·a − 1.2915·b = 0.384013

4. cube

l = 0.369462³ = 0.050432
m = 0.362402³ = 0.047596
s = 0.384013³ = 0.056629

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.061245
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.040916
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.063009

6. linear → sRGB, × 255

R = 0.27451 × 255 = 70.00 → 70
G = 0.22353 × 255 = 57.00 → 57
B = 0.27843 × 255 = 71.00 → 71

7. RGB → HEX
```
