Step-by-step math

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

1. input
```
oklch(0.55340 0.01161 58.071)
```

2. OKLCH → Oklab

a = C·cos H = 0.00614
b = C·sin H = 0.00985

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.557960
m′ = L − 0.1056·a − 0.0639·b = 0.552123
s′ = L − 0.0895·a − 1.2915·b = 0.540125

4. cube

l = 0.557960³ = 0.173704
m = 0.552123³ = 0.168309
s = 0.540125³ = 0.157573

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.187823
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.165130
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.149954

6. linear → sRGB, × 255

R = 0.47059 × 255 = 120.00 → 120
G = 0.44313 × 255 = 113.00 → 113
B = 0.42352 × 255 = 108.00 → 108

7. RGB → HEX
```
#78716C
