VistaStyleBuilder

Does anyone know which entry corresponds to the marked region in the ""-dialogue? Instead of light gray, it should be grey like the other regions of the dialogue.

I tried as described in "Complete Guide to Theme Building.pdf", but no color changed neither in the "Open"-Dialogue nor in the "Save as"-Dialogue.

This problem just occurs with Build 1909 (1903?) and just in the Save-As-dialog box, at least in 1709 everything is one unique color. Haven't tested it with other builds.
I am NOT using Dark Theme.

Little problem: What about the white rectangle between the horizontal and vertical scroll bar? Is it possible to change its color?

Windows 10 Dark Mode > Explorer & Shell > Shell > PreviewPaneControl > CommonItemsDialog:Edit > Background
(I don't know why this is listed as being in Dark Mode but  it is....)
Buttons, Boxes, & Controls > Scroll Bars & Trackers > ScrollBar > FillColor

Thank you, it works!

This doesn't change the corner at the right, but the one on the tree side.
And strangely enough it also changes the color of the 'size corner'
Well, I will let it as it is - white.

Try giving the Fillcolor and Buttons, Boxes, & Controls > Scroll Bars & Trackers > ScrollBar > SizeBox two different colors and see what happens.

The color of the right bottom corner is the same as the one for the background on the right side, in the "Complete Guide to Theme Building.pdf" on page 1, point 3:
I don't believe that it is possible to change both colors independently from each other.

But strange thing: Windows 10 with Aero and Windows 7 with Classic Theme show both corners with different colors, whereas Windows XP has got the same color (grey) for both corners :-)
(the company I am working for still uses some old computers with original XP and 7)

Just make the FillColor and SizeBox the same color.

The white square on the right is actually Buttons, Boxes, & Controls > Scroll Bars & Trackers > ScrollBar > SizeBox:

Here the FillColor and SizeBox are the same color:

I don't understand that:

The size-box corner (orange colored rectangle) and the corner at the navigation pane (blue rectangle) are not necessary the same corner (?).
