Step-by-step math

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

1. input
```
oklch(0.45911 0.18352 14.559)
```

2. OKLCH → Oklab

a = C·cos H = 0.17763
b = C·sin H = 0.04613

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.539466
m′ = L − 0.1056·a − 0.0639·b = 0.437414
s′ = L − 0.0895·a − 1.2915·b = 0.383636

4. cube

l = 0.539466³ = 0.156997
m = 0.437414³ = 0.083691
s = 0.383636³ = 0.056462

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.376254
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.000000
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.036887

6. linear → sRGB, × 255

R = 0.64705 × 255 = 165.00 → 165
G = 0.00000 × 255 = 0.00 → 0
B = 0.21176 × 255 = 54.00 → 54

7. RGB → HEX
```
#A50036
```
