How to Use Hero Image Overlay Designer
- 1 Select a dark color (usually black or dark brand blue) for the overlay.
- 2 Slide the 'Opacity' until the 'Heading Text' in the preview becomes clearly legible.
- 3 Copy the resulting 'rgba' value.
- 4 Apply this color to a pseudo-element (like ::after) or a dedicated div that sits between your background image and your text content.
Why This Matters
Using a photograph as a background for a website header (Hero section) is a popular design choice, but it often makes the text unreadable due to varying colors in the image. If you put white text over a light part of the photo, it disappears. Designers traditionally solve this by adding a semi-transparent 'overlay' on top of the image. Choosing the right opacity to balance 'image visibility' and 'text legibility' is a trial-and-error process that takes time.
