Before you finish
A quick check makes a better result.
OutMonkey is built to be simple enough for someone doing this once and useful enough for someone who does it every day.
Good to know
Use the number, then use your eyes.
A passing contrast result is useful, but also look at the real text size, weight, background and surrounding colours. Readability is the goal, not just the score.
A checker tells you what it can measure; it does not replace a final human look. Use the result to make the next decision, not as a guarantee.
In plain English
You do not need to be an expert.
You do not need to be a designer to use these checks. If text feels faint or difficult to read, choose a clearer combination even when the numbers are technically acceptable.
Use contrast checks as a floor for readability, not the whole accessibility story.
