Step-by-step math

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

1. input
```
oklch(0.78680 0.11622 191.558)
```

2. OKLCH → Oklab

a = C·cos H = -0.11386
b = C·sin H = -0.02329

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.736646
m′ = L − 0.1056·a − 0.0639·b = 0.800306
s′ = L − 0.0895·a − 1.2915·b = 0.827062

4. cube

l = 0.736646³ = 0.399740
m = 0.800306³ = 0.512589
s = 0.827062³ = 0.565737

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.064809
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.637590
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.603819

6. linear → sRGB, × 255

R = 0.28236 × 255 = 72.00 → 72
G = 0.81960 × 255 = 209.00 → 209
B = 0.80000 × 255 = 204.00 → 204

7. RGB → HEX
```
#48D1CC
