Step-by-step math

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

1. input
```
oklch(0.14690 0.00413 49.250)
```

2. OKLCH → Oklab

a = C·cos H = 0.00270
b = C·sin H = 0.00313

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.148644
m′ = L − 0.1056·a − 0.0639·b = 0.146416
s′ = L − 0.0895·a − 1.2915·b = 0.142618

4. cube

l = 0.148644³ = 0.003284
m = 0.146416³ = 0.003139
s = 0.142618³ = 0.002901

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.003677
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.003035
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.002732

6. linear → sRGB, × 255

R = 0.04706 × 255 = 12.00 → 12
G = 0.03922 × 255 = 10.00 → 10
B = 0.03530 × 255 = 9.00 → 9

7. RGB → HEX
```
#0C0A09
```
