Also known as: Tailwind purple-400

oklch(0.71003 0.19609 307.109) → #C27AFF

Values are shown at full precision, so converting back gives exactly #c27aff. 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(0.71003 0.19609 307.109)
```

2. OKLCH → Oklab

a = C·cos H = 0.11831
b = C·sin H = -0.15638

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.723172
m′ = L − 0.1056·a − 0.0639·b = 0.707527
s′ = L − 0.0895·a − 1.2915·b = 0.901405

4. cube

l = 0.723172³ = 0.378204
m = 0.707527³ = 0.354184
s = 0.901405³ = 0.732420

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.539468
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.194617
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.999966

6. linear → sRGB, × 255

R = 0.76078 × 255 = 194.00 → 194
G = 0.47843 × 255 = 122.00 → 122
B = 0.99998 × 255 = 255.00 → 255

7. RGB → HEX
```
#C27AFF
```
