           Summary: CSS Color parsing does no detect invalid color
                    identifiers.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jfernandez at igalia.com


Current implementation of the CSSParser::parseSystemColor assumes that if a valid cssValueKeywordID is got from the color string then it has to be a valid color. Such assumption is wrong and lead to many bugs and layout test failures. On example of these failures is the one detected after trying the patch for the bug #134419, which adds a new ValueKey for the "true" string. This string is part of the invalid values testing case of the canvas-color-serialization.html Layout test.
