Debugging HD color with the Styles pane
New CSS color types and spaces are coming to the web! It is equally exciting that DevTools introduced new tools to help developers create, convert and debug High Definition color.
The Styles pane now supports 12 new color spaces and 7 new gamuts as outlined in the CSS Color Level 4 specification. See High Definition CSS Color Guide for a comprehensive understanding of color options available on the web.
Here are examples of CSS color definitions with color(), lch(), oklab() and color-mix().
When using the color-mix() function, you can view the final color output in the Computed pane.
The color picker supports all the new color spaces with more features. For example, click on the color swatch of color(display-03 1 0 1). A gamut boundary line has also been added, distinguishing between the sRGB and display-p3 gamuts for a clearer understanding of your selected color's gamut.
DevTools supports converting colors between color formats. Use the Change Color Format icon to access the conversion popup, or simply use the Shift + click on a color swatch in the Styles pane.
When converting, it's important to know if the conversion was clipped to fit the space. DevTools puts a warning icon next to the converted color that alerts you to this clipping.
In addition, you can pick colors from your screen with the new shortcut. Press 'C' to activate the eye dropper and hit Escape to deactivate it.
Finally, the Color format setting is now deprecated to make room for the new HD color format.

Enhanced breakpoint UX
The redesigned Breakpoints pane allows you to have quick access to commonly used features, in particular, deactivating, editing, and removing breakpoints.
These are some highlights:
-
Both pause exception options moved to the Breakpoints pane and labeled with text to make it more self-explanatory.
-
Breakpoints are grouped by file, ordered by line or column numbers, and are collapsible.
-
There are new options to deactivate, remove, and edit breakpoints when hovering over a breakpoint or file.
-
Click the edit breakpoint button to open the breakpoint editor. From here, you can enter the breakpoint condition or switch to a logpoint.
See JavaScript debugging reference to learn how to debug with DevTools.

Customizable Recorder shortcuts
Use keyboard shortcuts to record and replay user flows quicker.
The Recorder introduces a few convenient keyboard shortcuts for faster recording and replaying of user flows.
Don’t remember the shortcuts? No problem, click the ? button to view all the shortcuts at any time.
You can even customize these shortcuts via the Settings menu.
If you're working in a different panel and want to start a user flow recording, use the Create a new recording command from the Command Menu in DevTools to get started.

Better syntax highlight for Angular

Chromium issues: 1385374, 1385678
