black and white BlendMode color ColorCircle ColorPicker donut palette RGB
Color Picker Not Boring Anymore
For my next project, I needed some lightweight color picker that would be usable but not boring. Nice challenge. So I have created ColorCircle class that may work as a color picker while it dispatches all the necessary ColorCircleEvent-s. I made this class a little dynamic, so you can create custom color pickers on runtime using RGB palette, Black to White fade, solid color or current color with any defined radius (inner + outer) you want.
To create donut shapes I have used shape with lineStyle+drawCircle+cacheAsBitmap drawed over original graphics using BlendMode.ALPHA. To browse RGB pelette there is a paletteColor() method that crawls all color spectrum based on position (0 to 1).

alpha BlendMode Layer TextField transparency
Quick tip: Alpha On TextFields
When targeting your movie into flash player 9 (or lower), you can fall into issues with text transparency. If TextField contains not embedded font, by default it will not render transparency (alpha) correctly. Luckily, there is a solution for that, as simple as setting blendMode to “layer” parameter to your TextField. This solution was mentioned on Glenn Gervais blog plus there are some other techniques mentioned in comments, for example applying BlurFilter(0, 0) or cacheAsBitmap=true. Thankfully, once you start targeting Flash Player 10, you won’t need any sort of hacks.
