Question 1

What does it mean to invert a color?

Accepted Answer

Inverting a color (also called photographic negative) flips each color channel: 255 minus the original value. White (255,255,255) becomes black (0,0,0), red (255,0,0) becomes cyan (0,255,255), and so on.

Question 2

How do I create a dark mode alternative?

Accepted Answer

The inverted color is a quick way to find a high-contrast counterpart. Inverting a light background gives you a dark color suitable for dark mode. You may want to fine-tune the result for visual comfort.

Question 3

Does color inversion help with accessibility?

Accepted Answer

Inversion is useful for creating high-contrast pairs but can shift hue and reduce readability for text. For accessibility, use a proper color contrast tool (WCAG AA/AAA) rather than relying on inversion.

Question 4

Is this the same as CSS filter:invert(100%)?

Accepted Answer

The CSS filter invert(100%) inverts all color channels just like this tool. However, CSS filter also inverts images and other elements, while this tool processes a single color value precisely.
