Inspect and debug HD and non-HD colors with the Color Picker

The Color Picker provides a GUI for changing color and *-color declarations and lets you create, convert, and debug non-HD and HD colors with a click.

For a deep dive on the new color spaces, see High Definition CSS Color Guide.

# Open the Color Picker and change colors

Use the Color Picker to change color values with a click:

1. Select an element in the Elements panel.

2. In the Styles pane, find the color or *-color declaration you want to change.

   To the left of each color or *-color value, there is a small square icon with a preview of that color.

   

   This example shows two intersected circles next to the color-mix() function: . The intersection is a preview of the resulting color.

   To inspect the computed value, use the Computed pane.

3. Click the preview square next to a color to open the Color Picker.

4. To change the color, use any of the UI elements of the Color Picker.

# Color Picker elements

Here's a description of each of the UI elements of the Color Picker:

   • oklab(X X X / .X)

   Or a space defined by the color(<color_space> X X X) function.

# Convert colors

When you switch between color spaces with the Display value switcher, DevTools automatically converts the values.

2. Expand the Contrast ratio section.

3. Use the suggested color that complies with a guideline:

   • In the Shades preview at the top, drag the Color circle below the corresponding line.
