Step-by-step math

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

1. input
```
oklch(0.65493 0.26134 356.945)
```

2. OKLCH → Oklab

a = C·cos H = 0.26097
b = C·sin H = -0.01393

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.755356
m′ = L − 0.1056·a − 0.0639·b = 0.628271
s′ = L − 0.0895·a − 1.2915·b = 0.649565

4. cube

l = 0.755356³ = 0.430978
m = 0.628271³ = 0.247994
s = 0.649565³ = 0.274074

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.999996
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.006989
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.291761

6. linear → sRGB, × 255

R = 1.00000 × 255 = 255.00 → 255
G = 0.07838 × 255 = 19.99 → 20
B = 0.57646 × 255 = 147.00 → 147

7. RGB → HEX
```
#FF1493
```
