Design utilities help translate colors, dimensions and layout values into reusable settings. A color representation or size calculation is only useful when its units and intended display context are clear.
Common questions
Are colors identical on every display?
No. Display calibration, color management and viewing conditions can change appearance. Numeric color conversion does not control those conditions.
Does a computed contrast ratio describe the whole design?
A ratio compares specified foreground and background colors. Transparency, images, font size and other visual choices can change the actual reading experience.
