Step-by-step math

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

1. input
```
oklch(0.66676 0.25906 322.150)
```

2. OKLCH → Oklab

a = C·cos H = 0.20456
b = C·sin H = -0.15896

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.713531
m′ = L − 0.1056·a − 0.0639·b = 0.655317
s′ = L − 0.0895·a − 1.2915·b = 0.853748

4. cube

l = 0.713531³ = 0.363277
m = 0.655317³ = 0.281419
s = 0.853748³ = 0.622284

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.693862
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.061244
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.863141

6. linear → sRGB, × 255

R = 0.85098 × 255 = 217.00 → 217
G = 0.27450 × 255 = 70.00 → 70
B = 0.93725 × 255 = 239.00 → 239

7. RGB → HEX
```
#D946EF
