Embedded Wizard Studio: Color select dialog
With this dialog you can select or modify a color value easily.
Color select dialog
In Embedded Wizard colors are represented platform independently as composed of the components red, green, blue and alpha by following the additive color model. In this model the individual intensity of the components red, green and blue is added together resulting a broad array of colors. The component alpha, in turn, determines the actual opacity of the color. Every of the four components can assume a value in range 0 .. 255, whereby the value 255 means the full intensity of the respective component. See color data type.
