Step-by-step math

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

1. input
```
oklch(0.55404 0.01355 59.397)
```

2. OKLCH → Oklab

a = C·cos H = 0.00690
b = C·sin H = 0.01166

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.559291
m′ = L − 0.1056·a − 0.0639·b = 0.552567
s′ = L − 0.0895·a − 1.2915·b = 0.538361

4. cube

l = 0.559291³ = 0.174950
m = 0.552567³ = 0.168716
s = 0.538361³ = 0.156034

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.191201
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.165136
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.147034

6. linear → sRGB, × 255

R = 0.47451 × 255 = 121.00 → 121
G = 0.44314 × 255 = 113.00 → 113
B = 0.41962 × 255 = 107.00 → 107

7. RGB → HEX
```
#79716B
