            Bug ID: 228315
           Summary: layout tests should be runnable with non-sRGB color
                    profiles
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests

Currently if you write a layout test that compares say

  <div style="width: 100px; height: 100px; background-color: red;"></div>

with

  <div style="width: 100px; height: 100px; background-color: color(display-p3 1 0 0 0);"></div>

then the test will pass.  We should probably have a way to run a test in a way that doesn't cause wide gamut colors to get clamped down to sRGB.

On macOS, we switch the display to an sRGB color profile and run all tests in this mode, but it looks like it's not sufficient to leave a Display P3 display with its factory color profile for the tests to pass.
