Frequently Asked Questions
What is a Contrast Ratio?
A contrast ratio is a numerical value that represents the difference in brightness between two colors. In web banners, a higher ratio means your text stands out more clearly against the background.
What is the WCAG standard?
The Web Content Accessibility Guidelines (WCAG) recommend a minimum contrast ratio of 4.5:1 for normal text and 7:1 for high-accessibility standards. For advertising banners, hitting 7:1 ensures your message is readable even on small, low-brightness mobile screens.
Why should I use high-contrast colors in ads?
Digital ads are often seen for less than a second as a user scrolls. If your text is “muted” or lacks contrast, the user’s brain won’t process the message, leading to wasted impressions and a lower CTR.
Does color choice affect conversion psychology?
Absolutely. High-contrast colors like Red or Orange can drive urgency, while Navy and White project trust. Use the presets in this tool to quickly test colors that match your campaign’s psychological goal.
