Step-by-step math

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

1. input
```
oklch(0.28104 0.09244 268.132)
```

2. OKLCH → Oklab

a = C·cos H = -0.00301
b = C·sin H = -0.09239

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.259907
m′ = L − 0.1056·a − 0.0639·b = 0.287258
s′ = L − 0.0895·a − 1.2915·b = 0.400631

4. cube

l = 0.259907³ = 0.017557
m = 0.287258³ = 0.023704
s = 0.400631³ = 0.064303

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.008024
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.017642
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.093058

6. linear → sRGB, × 255

R = 0.08628 × 255 = 22.00 → 22
G = 0.14118 × 255 = 36.00 → 36
B = 0.33725 × 255 = 86.00 → 86

7. RGB → HEX
```
