Step-by-step math

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

1. input
```
oklch(0.75764 0.15904 55.934)
```

2. OKLCH → Oklab

a = C·cos H = 0.08909
b = C·sin H = 0.13175

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.821380
m′ = L − 0.1056·a − 0.0639·b = 0.739823
s′ = L − 0.0895·a − 1.2915·b = 0.579518

4. cube

l = 0.821380³ = 0.554156
m = 0.739823³ = 0.404934
s = 0.579518³ = 0.194626

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.964699
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.287437
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.045183

6. linear → sRGB, × 255

R = 0.98432 × 255 = 251.00 → 251
G = 0.57255 × 255 = 146.00 → 146
B = 0.23529 × 255 = 60.00 → 60

7. RGB → HEX
```
#FB923C
```
