Recently I found, that the color for a panel (TPanel) isn't as brilliant as it should be. It's only a problem for TPanel, not for other components: white is not white but light grey, lime and red are a little bit darker. Lime and red are not critical, but white should be white for every component.
This behaviour is reproducable on Laz 2.0.6 only, 2.0.2 was quite OK.
