Step-by-step math

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

1. input
```
oklch(0.55754 0.25249 302.321)
```

2. OKLCH → Oklab

a = C·cos H = 0.13500
b = C·sin H = -0.21337

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.564998
m′ = L − 0.1056·a − 0.0639·b = 0.556914
s′ = L − 0.0895·a − 1.2915·b = 0.821025

4. cube

l = 0.564998³ = 0.180360
m = 0.556914³ = 0.172729
s = 0.821025³ = 0.553438

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.291773
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.033105
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.822802

6. linear → sRGB, × 255

R = 0.57647 × 255 = 147.00 → 147
G = 0.20000 × 255 = 51.00 → 51
B = 0.91766 × 255 = 234.00 → 234

7. RGB → HEX
```
#9333EA
