CAD tip # 6546:
Question
A
If you need to create a partially "transparent" toolbar icons, you cannot use standard ways of PNG format with alpha-channel or transparent GIF files - AutoCAD (up to 2014) supports only icons in the BMP format which doesn't work with transparency.
But you can use a trick - the color with the hue of 192-192-192 (RGB) used in BMP icons is interpreted by AutoCAD as "transparent". Since 2015 you can use PNG icons with transparency. Since 2017 the 192,192,192-trick doesn't work anymore and PNG is the only option for transparent icons.
