What is a transparent overlay?
A transparent overlay is a layer of hue used to creatively change the color of an image. Transparent overlays can be a single color or multicolor. Multicolor gradients can be radial, with one color in the center that fades into another at the edges, or linear, with colors that fade into each other from top to bottom or left to right.
Effective uses of transparent overlays.
Transparent overlays are a great way to showcase brand colors in background images or hero images (prominent images in a design). A solid color background can also be effective, but an image with a color overlaid onto it can be more dynamic and have more narrative power.
Stock photos, vector graphics, and clip art are, by definition, generic. Use a transparent overlay of your brand colors to turn these resources into branded assets (images that align with a company’s brand identity).
