Allow colors to be parseable strings (RGB, HSL, Hex)

[janmartenjongerius]

Allow for colors to be values you'd enter in an image manipulation program or simple CSS stylesheets.

As far as I grasp the subject, the models already accept HSL, only by splitting off the Lightness part off as CT.

RGB and Hex (#000) colors can be translated to HSL, which in turn requires minimal translation to the native colors. Perhaps there exists a ratio between CT and L, but that's something one can look up or reverse engineer.

It would allow for the following code:

$Lo_HueState->setColor(
  array(
    'name' => 'white',
    'hex' => '#FFF',
    // X, Y
    'xy' => array(0.143, 0.451)
  )
);

See https://github.com/sgry/svnhue/issues/2 for a reference to the structure I used in this example.

Additionally you could add a translation from the current color to either color mode, through methods like:

• toHSL()
• toRGB()
• toHexaDecimal or, as it is the most common color in CSS, toCSS() which has my vote against it, but there you go.

If I knew how to convert RGB colors to either hue/sat or xy it would aready be in there. The Hue bridge doesn't use proper HSL as far as I understood it. The CT colormode is only for different whites. Cold (154) to warm (500). My knowledge in color stuff is very limited. I will leave this issue open and look into it! Thanks!

The official API by Philips just got released. Ars Technica has a little paragraph about the colorsettings: http://arstechnica.com/gadgets/2013/03/philips-delivers-promised-dev-docs-for-colorful-hue-led-lights/

Seems I have plans for next weekend ;-)
