I like to fill the box a chip uses with a color as it looks better to

my publishers.

First, tell your publisher to get over it.

If that fails, you should be able to define your own layer and set it to

any color you like.  Then add a rectangle of that layer over the chip.

I've never actually done this, and don't know if custom layers can be

defined in the package, but it seems it should work.

I often defune custom layers in the library - it works well for me.

I use 8 custom layers with 8 different colors for "highlighting" parts

on a board printout for manual assembly of SMT prototypes.  I do this in

the PCB (actually on a separate copy of the .brd file) and do not modify

the library parts.  A ULP is helpful to automate the process.

Would appreciate it if you would explain more fully how your part

highlighting works.

Thanks

explain more fully how your part highlighting works.

Imagine a silkscreen or tDocu printout that you use multiple highlighter

pens to mark all parts that have the same value with the same colour.  I

think some other CAD packages may have this type of assembly aid print out.

I set 8 user defined layers each with its own colour assigned in White

Palette colours 56 to 63.  I have Eagle draw a "highlighting" rectangle

on the appropriate user layer (colour) with its corners on the corners

of the (element) package area.  I end up with multiple tDocu or

silkscreen printouts/PNG/PDFs with 8 part values highlighted per page.

I found it is not perfect as I needed to smash all the parts and accept

that the highlighting might "overlap" where parts are close together.  I

manually edit the text output of a mount-trace.ulp to help get useful

results.

Some experimenting produced results that our assembler/technician and I

found useful.

Regards,

Neil

Now back to the original post

I imagine that the different color is because a different palette is being

used for the schematic.

Likely WHITE for the library and  COLORED for the schematic

If so you need to get the color being used for the symbol fill into both

palettes and in the same position in those palettes.

The alpha channel of the colors should also be set to 255  as some

transparency, when using a colored background may be the color difference

you are detecting.

Thanks Warren,

I think you may be right.
