Problem Description

When attempting to import a BMP file for usage as an Icon and this image has only one single color like red, green, blue ect. its icon color changes to a different color than the original color.


This drawn rectangles were used for the images for icon creation.
The colors of the tool icons differ from the colors of their origins.

Steps to Resolve

For BMP images the color of the top left pixel in the image is used as the alpha/transparent color during import to an ico format. Please use a BMP file with a 1 pixel wide white border or just a small white square in the top left corner that tells MicroStation to use white as the transparent color.
