Block default colors

[Design_GT]

My blocks are solid colors,,when I copy or move it over a wht background jpeg or pdf in the drawing they change to different colors ..how do I change the negative color...ie   blue block,,,,the yellow negative is too light to see when moving or copying over jpeg?

Is your block's content set to BYLAYER or BYBLOCK?

[Design_GT]

?color changes regardless what the layer setting is , it not permanent change, just changes when block is hovering over a white background jpeg/pdf, once you place the block it is blue.

maybe its a graphics card thing?

No color changes happen here at all when I drag a colored block over a white-background PDF, so back to my question... .

Or... select your PDF, open PROPERTIES and change the entry ADJUST COLORS FOR BACKGROUND to yes.
