Step-by-step math

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

1. input
```
oklch(0.59597 0.12742 163.225)
```

2. OKLCH → Oklab

a = C·cos H = -0.12200
b = C·sin H = 0.03678

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.555554
m′ = L − 0.1056·a − 0.0639·b = 0.606500
s′ = L − 0.0895·a − 1.2915·b = 0.559392

4. cube

l = 0.555554³ = 0.171466
m = 0.606500³ = 0.223096
s = 0.559392³ = 0.175045

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.001515
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.304987
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.141260

6. linear → sRGB, × 255

R = 0.01958 × 255 = 4.99 → 5
G = 0.58823 × 255 = 150.00 → 150
B = 0.41176 × 255 = 105.00 → 105

7. RGB → HEX
```
#059669
