System colors do not give correct RGB values

[Moshe_Ben-Tzion]

When using the IMAQ integer to color value function, I get correct RGB values for colors chosen via a color box control  - except if the colors are selected from the “system colors”. Is this supposed to happen? The RGB values for the system "White" is: 0, 0, 9.

That function does look at the most significant byte. Try wiring the system color to a "Split Number" (numerics "Dat manipulation) to split the I32 to two I16 and then again to get four I8s.

You will find that the "other" bytes has a "1".

System colors are special.
