Step-by-step math

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

1. input
```
oklch(0.49812 0.26344 301.680)
```

2. OKLCH → Oklab

a = C·cos H = 0.13835
b = C·sin H = -0.22419

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.504574
m′ = L − 0.1056·a − 0.0639·b = 0.497831
s′ = L − 0.0895·a − 1.2915·b = 0.775273

4. cube

l = 0.504574³ = 0.128462
m = 0.497831³ = 0.123380
s = 0.775273³ = 0.465976

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.223227
G = −1.2684·l + 2.6098·m − 0.3413·s = -0.000001
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.708380

6. linear → sRGB, × 255

R = 0.50980 × 255 = 130.00 → 130
G = 0.00000 × 255 = 0.00 → 0
B = 0.85883 × 255 = 219.00 → 219

7. RGB → HEX
```
#8200DB
