Step-by-step math

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

1. input
```
oklch(0.70167 0.32249 328.363)
```

2. OKLCH → Oklab

a = C·cos H = 0.27456
b = C·sin H = -0.16916

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.773985
m′ = L − 0.1056·a − 0.0639·b = 0.683488
s′ = L − 0.0895·a − 1.2915·b = 0.895565

4. cube

l = 0.773985³ = 0.463658
m = 0.683488³ = 0.319295
s = 0.895565³ = 0.718277

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.999979
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.000000
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.999996

6. linear → sRGB, × 255

R = 0.99999 × 255 = 255.00 → 255
G = 0.00000 × 255 = 0.00 → 0
B = 1.00000 × 255 = 255.00 → 255

7. RGB → HEX
```
#FF00FF
