Description
from the App Store listing
Colour Well is an app to test colour combinations, and display useful colour information.
You can see how your chosen colour:
- mixes with common colours;
- changes with different hues, saturations & lightnesses;
- contrasts against black, white, and a second chosen colour.
For your two chosen colours, Red-Green-Blue colour information will be displayed (useful for coding, web design and for paint programs) as:
- a hex triplet
- RGB values: ratios (0.0-1.0)
- RGB values: bytes (0-255)
