Step-by-step math

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

1. input
```
oklch(0.70487 0.18672 47.604)
```

2. OKLCH → Oklab

a = C·cos H = 0.12590
b = C·sin H = 0.13789

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.784525
m′ = L − 0.1056·a − 0.0639·b = 0.682775
s′ = L − 0.0895·a − 1.2915·b = 0.515517

4. cube

l = 0.784525³ = 0.482859
m = 0.682775³ = 0.318297
s = 0.515517³ = 0.137003

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.947301
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.171440
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.008026

6. linear → sRGB, × 255

R = 0.97647 × 255 = 249.00 → 249
G = 0.45098 × 255 = 115.00 → 115
B = 0.08629 × 255 = 22.00 → 22

7. RGB → HEX
```
#F97316
