Step-by-step math

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

1. input
```
oklch(0.38606 0.05902 188.416)
```

2. OKLCH → Oklab

a = C·cos H = -0.05838
b = C·sin H = -0.00864

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.361056
m′ = L − 0.1056·a − 0.0639·b = 0.392775
s′ = L − 0.0895·a − 1.2915·b = 0.402440

4. cube

l = 0.361056³ = 0.047068
m = 0.392775³ = 0.060594
s = 0.402440³ = 0.065179

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.006509
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.076187
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.068479

6. linear → sRGB, × 255

R = 0.07449 × 255 = 18.99 → 19
G = 0.30589 × 255 = 78.00 → 78
B = 0.29020 × 255 = 74.00 → 74

7. RGB → HEX
```
#134E4A
