Step-by-step math

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

1. input
```
oklch(0.82759 0.10128 230.318)
```

2. OKLCH → Oklab

a = C·cos H = -0.06467
b = C·sin H = -0.07795

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.785138
m′ = L − 0.1056·a − 0.0639·b = 0.839394
s′ = L − 0.0895·a − 1.2915·b = 0.934042

4. cube

l = 0.785138³ = 0.483992
m = 0.839394³ = 0.591422
s = 0.934042³ = 0.814890

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.205073
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.651416
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.973471

6. linear → sRGB, × 255

R = 0.49019 × 255 = 125.00 → 125
G = 0.82746 × 255 = 211.00 → 211
B = 0.98825 × 255 = 252.00 → 252

7. RGB → HEX
```
#7DD3FC
