Step-by-step math

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

1. input
```
oklch(0.29052 0.14324 302.717)
```

2. OKLCH → Oklab

a = C·cos H = 0.07742
b = C·sin H = -0.12052

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.295197
m′ = L − 0.1056·a − 0.0639·b = 0.290043
s′ = L − 0.0895·a − 1.2915·b = 0.439236

4. cube

l = 0.295197³ = 0.025724
m = 0.290043³ = 0.024400
s = 0.439236³ = 0.084741

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.043734
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.002125
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.127433

6. linear → sRGB, × 255

R = 0.23137 × 255 = 59.00 → 59
G = 0.02745 × 255 = 7.00 → 7
B = 0.39215 × 255 = 100.00 → 100

7. RGB → HEX
```
#3B0764
