Step-by-step math

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

1. input
```
oklch(0.50397 0.12809 245.460)
```

2. OKLCH → Oklab

a = C·cos H = -0.05320
b = C·sin H = -0.11652

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.457740
m′ = L − 0.1056·a − 0.0639·b = 0.517026
s′ = L − 0.0895·a − 1.2915·b = 0.659214

4. cube

l = 0.457740³ = 0.095908
m = 0.517026³ = 0.138209
s = 0.659214³ = 0.286470

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.000002
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.141261
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.391559

6. linear → sRGB, × 255

R = 0.00003 × 255 = 0.01 → 0
G = 0.41176 × 255 = 105.00 → 105
B = 0.65881 × 255 = 168.00 → 168

7. RGB → HEX
```
#0069A8
