Step-by-step math

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

1. input
```
oklch(0.65592 0.21177 354.308)
```

2. OKLCH → Oklab

a = C·cos H = 0.21073
b = C·sin H = -0.02100

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.734906
m′ = L − 0.1056·a − 0.0639·b = 0.635017
s′ = L − 0.0895·a − 1.2915·b = 0.664189

4. cube

l = 0.734906³ = 0.396913
m = 0.635017³ = 0.256068
s = 0.664189³ = 0.293005

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.838788
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.064808
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.318551

6. linear → sRGB, × 255

R = 0.92548 × 255 = 236.00 → 236
G = 0.28236 × 255 = 72.00 → 72
B = 0.60000 × 255 = 153.00 → 153

7. RGB → HEX
```
#EC4899
