Step-by-step math

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

1. input
```
oklch(0.44459 0.17737 26.787)
```

2. OKLCH → Oklab

a = C·cos H = 0.15834
b = C·sin H = 0.07994

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.524595
m′ = L − 0.1056·a − 0.0639·b = 0.422772
s′ = L − 0.0895·a − 1.2915·b = 0.327185

4. cube

l = 0.524595³ = 0.144369
m = 0.422772³ = 0.075564
s = 0.327185³ = 0.035025

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.346698
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.002127
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.006050

6. linear → sRGB, × 255

R = 0.62352 × 255 = 159.00 → 159
G = 0.02749 × 255 = 7.01 → 7
B = 0.07060 × 255 = 18.00 → 18

7. RGB → HEX
```
#9F0712
