Checking the Contrast or Legibility of a Figure

Viewing in grayscale ensures your figure is legible for low-resolution screens, black -and-white prints, and color-blind audiences.

BioRender has a built-in “View in Grayscale” feature that allows you to check the contrast of an illustration. Contrast refers to how easily you can distinguish one object from another, such as text overlaid on a shape.

We recommend checking your contrast before exporting since high-contrast illustrations are easier to understand at a quick glance. This feature also helps determine if your illustration will be legible in various scenarios:

  • When viewed on a low-resolution screen

  • When printed in black and white

  • When viewed by color-blind audiences

You can tell if your illustration has high contrast when you can still see all your icons and objects clearly in grayscale preview, and nothing disappears into the background or blends in.

For example:

How to View Your Illustration in Grayscale
