Reference TColorTextMode

TAdvancedColorDialogForm lets the user pick a color with alpha using a hue and saturation picker, an alpha picker, and red, green, blue, and alpha slide edits. A button under the slide edits switches them between red, green, and blue or hue, saturation, and lightness. A grid of common colors is shown on the right, and below it the color is shown as text which can be edited. The button next to the text cycles between Delphi, HTML, and css rgba text. A row of custom colors along the bottom are saved between uses. Click a custom color to use it, or right click it to store the current color there.
