public class PaletteTab extends Composite
The Palette tab of the SWT color chooser (CC-COLOR-CHOOSER-SWT-PANELS, 2026-10-10): the PaletteEntries in a table of three columns (the header hidden) - a group as a bold header in the first column that cannot be chosen, an entry with its two swatches (light, dark) and its path in the first column, its light hex value in the second and its dark hex value in the third, so that the values align (CC-COLOR-CHOOSER-SWT-SWITCH, the owner's addition of 2026-10-10; the first version wrote path and values into one cell). Choosing an entry sets the literal of the Designer's saved scheme in the chooser and records the reference; a change of the color made elsewhere clears the selection, and with it the reference. The swatch images paint on the theme's field background with a frame in its border color and an unresolved value's cross in its disabled foreground (ChooserColors, CC-FIX-COLOR-CHOOSER-DARK); the table itself is themed by Eclipse.
