Frequently Asked Questions
How accurate is the color extraction? ▼
The algorithm samples thousands of distinct pixels across the image canvas, ensuring dominant background and accent colors are accurately identified.
Can I copy individual RGB and HEX values? ▼
Yes. Each swatch card includes one click buttons to copy either the #HEX code or the rgb(...) string.
Does this work on transparent PNG logos? ▼
Yes. Fully transparent pixels (alpha < 0.1) are automatically filtered out so they do not distort the palette.
