Also known as: Tailwind red-700

oklch(0.50949 0.20858 28.513) → #C10007

Values are shown at full precision, so converting back gives exactly #c10007. The rounded form is what you normally paste into CSS.

Step-by-step math

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

1. input
```
oklch(0.50949 0.20858 28.513)
```

2. OKLCH → Oklab

a = C·cos H = 0.18328
b = C·sin H = 0.09957

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.603618
m′ = L − 0.1056·a − 0.0639·b = 0.483785
s′ = L − 0.0895·a − 1.2915·b = 0.364499

4. cube

l = 0.603618³ = 0.219931
m = 0.483785³ = 0.113229
s = 0.364499³ = 0.048427

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.533260
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.000001
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.002125

6. linear → sRGB, × 255

R = 0.75685 × 255 = 193.00 → 193
G = 0.00001 × 255 = 0.00 → 0
B = 0.02746 × 255 = 7.00 → 7

7. RGB → HEX
```
#C10007
```
