About the Colour and contrast checker.
What contrast ratio should text have?
WCAG asks for at least 4.5 to 1 for normal text and 3 to 1 for large text at level AA.
Why does it matter?
Low contrast is hard to read, especially on phones in bright light and for people with low vision.
Does it give RGB and HSL?
Yes, for the colour you enter.
