Step-by-step math

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

1. input
```
oklch(0.55416 0.04599 257.526)
```

2. OKLCH → Oklab

a = C·cos H = -0.00993
b = C·sin H = -0.04490

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.540532
m′ = L − 0.1056·a − 0.0639·b = 0.558076
s′ = L − 0.0895·a − 1.2915·b = 0.613042

4. cube

l = 0.540532³ = 0.157930
m = 0.558076³ = 0.173812
s = 0.613042³ = 0.230394

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.122134
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.174645
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.270499

6. linear → sRGB, × 255

R = 0.38431 × 255 = 98.00 → 98
G = 0.45490 × 255 = 116.00 → 116
B = 0.55686 × 255 = 142.00 → 142

7. RGB → HEX
```
#62748E
