image colors

[Syb H]

When projecting my power point presentation, the colors in my jpeg or tif
images are not the same on the screen vs. my computer. They are not picture
images, but plan sheets made in AutoCad. The blue is white, the green is gray
and the yellow is brown. I am using version 2003. Any suggestions?

Do you have these color problems only in PowerPoint or with anything
projected? Does this happen with just your computer or with other computers?
I could be wrong, but to me this sounds like a bad cable from your computer
to the projector (or a badly plugged in cable).

We tried two different computers and that got me wondering about the
projector as well. Throughout the slide show, all the picture images have the
correct color, it is just the slides made in AutoCad that were converted to
jpegs.

Can you export to PNG from AutoCad? That might give you better results
(though slightly larger files).

To get good help, you need to give good information. Now you mention JPEG
images, but previously you mentioned TIFF and GIF images also.

I'd do the following:
1) Check during the slideshow the view on the monitor simultaneously - if
it is wrong too, the problem is not in the projector
2) Check how any other application displays the files
3) I'd open the files in an image editor (any editor that you have) and
save them again. If that helps, the AutoCAD has made some bad files which
can be fixed this way
4) AutoCAD's saving of bitmap files can probably be adjusted. I'd look into
the checkings and look for any kind of anomalities, like use of indexed
color or low color depth (like 16 colors), uncommon color profiles, CMYK
etc...
