Step-by-step math

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

1. input
```
oklch(0.71919 0.16898 13.428)
```

2. OKLCH → Oklab

a = C·cos H = 0.16436
b = C·sin H = 0.03924

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.792801
m′ = L − 0.1056·a − 0.0639·b = 0.699334
s′ = L − 0.0895·a − 1.2915·b = 0.653803

4. cube

l = 0.792801³ = 0.498301
m = 0.699334³ = 0.342022
s = 0.653803³ = 0.279474

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.964685
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.165141
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.234558

6. linear → sRGB, × 255

R = 0.98431 × 255 = 251.00 → 251
G = 0.44315 × 255 = 113.00 → 113
B = 0.52158 × 255 = 133.00 → 133

7. RGB → HEX
```
#FB7185
