Step-by-step math

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

1. input
```
oklch(0.54206 0.03367 322.504)
```

2. OKLCH → Oklab

a = C·cos H = 0.02671
b = C·sin H = -0.02050

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.548225
m′ = L − 0.1056·a − 0.0639·b = 0.540549
s′ = L − 0.0895·a − 1.2915·b = 0.566139

4. cube

l = 0.548225³ = 0.164769
m = 0.540549³ = 0.157945
s = 0.566139³ = 0.181455

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.191197
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.141264
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.198062

6. linear → sRGB, × 255

R = 0.47450 × 255 = 121.00 → 121
G = 0.41177 × 255 = 105.00 → 105
B = 0.48235 × 255 = 123.00 → 123

7. RGB → HEX
```
#79697B
