Step-by-step math

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

1. input
```
oklch(0.75351 0.13899 232.661)
```

2. OKLCH → Oklab

a = C·cos H = -0.08430
b = C·sin H = -0.11051

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.696251
m′ = L − 0.1056·a − 0.0639·b = 0.769465
s′ = L − 0.0895·a − 1.2915·b = 0.903770

4. cube

l = 0.696251³ = 0.337518
m = 0.769465³ = 0.455582
s = 0.903770³ = 0.738199

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.039540
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.508877
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.938679

6. linear → sRGB, × 255

R = 0.21959 × 255 = 56.00 → 56
G = 0.74117 × 255 = 189.00 → 189
B = 0.97255 × 255 = 248.00 → 248

7. RGB → HEX
```
#38BDF8
