Step-by-step math

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

1. input
```
oklch(0.76885 0.16875 161.949)
```

2. OKLCH → Oklab

a = C·cos H = -0.16044
b = C·sin H = 0.05229

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.716544
m′ = L − 0.1056·a − 0.0639·b = 0.782448
s′ = L − 0.0895·a − 1.2915·b = 0.715676

4. cube

l = 0.716544³ = 0.367899
m = 0.782448³ = 0.479034
s = 0.715676³ = 0.366564

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = -0.000011
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.658389
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.287445

6. linear → sRGB, × 255

R = 0.00000 × 255 = 0.00 → 0
G = 0.83138 × 255 = 212.00 → 212
B = 0.57255 × 255 = 146.00 → 146

7. RGB → HEX
```
#00D492
