Hello whatwg!<br><br>Many developers, js libraries, and frameworks
interact with colors in a variety ways in their pages and apps. One
common action they perform in many of these interactions is to convert
colors between RGB and HEX. A fair amount of js is needed to do this
type of thing, see the following examples: <a href="http://www.google.com/search?q=convert+hex+to+rgb+javascript&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:unofficial&client=firefox-a#sclient=psy&num=10&hl=en&client=firefox-a&hs=pqr&rls=org.mozilla%3Aen-US%3Aunofficial&q=javascript+convert+hex+to+rgb&aq=f&aqi=g1&aql=&oq=javascript+convert+hex+to+rgb&gs_rfai=&pbx=1&fp=7b3e9e0669ddb0a1" target="_blank">converting hex to rgb in js</a><br>
<br>I propose that we provide a way for developers to get all color equivalents of a valid color string - red, #ff0, rgb(255, 0, 0).<br><br>Currently
to derive RGB or HEX values from a named css color there is even more
craziness required. You must create a dummy element, inject it into the
DOM, set styles, get the computed styles, and finally perform various
validity checks to ensure the correct output: Here is an implementation I
put together to convert named colors to RGB or HEX: <a href="http://people.mozilla.com/%7Edbuchner/demos/web/colordiscovery/index.html" target="_blank">named colors to hex and rgb</a> - try typing in 'red', 'magenta', etc.<br>
<br>The very fact that the colors can be converted via the
implementation I use, indicates the look-up is already present in
browsers, there is just nothing exposed to developers to take advantage
of it.<br><br>Thoughts?
