Step-by-step math

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

1. input
```
oklch(0.77241 0.17280 65.367)
```

2. OKLCH → Oklab

a = C·cos H = 0.07202
b = C·sin H = 0.15707

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.834853
m′ = L − 0.1056·a − 0.0639·b = 0.754777
s′ = L − 0.0895·a − 1.2915·b = 0.563106

4. cube

l = 0.834853³ = 0.581876
m = 0.754777³ = 0.429988
s = 0.563106³ = 0.178554

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.991120
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.323147
B = −0.0042·l − 0.7034·m + 1.7076·s = -0.000002

6. linear → sRGB, × 255

R = 0.99609 × 255 = 254.00 → 254
G = 0.60393 × 255 = 154.00 → 154
B = 0.00000 × 255 = 0.00 → 0

7. RGB → HEX
```
#FE9A00
```
