Is this only a problem with PHP/GD versions previous to 4.0.6/2.0.1?
Does the new ImageCreateTrueColor() function fix this issue?

That's something you would need to do in photoshop.
open your image, select save for web, look to the left of the image, you
should see some buttons and a black box. you need to click on the black
box, select the yellow you want, and then click ok. Then, click the
button above the yellow - that will select the eyedropper. Then, go to
the color palette opposite. click on the 3rd icon underneath it, which
allows you to add eyedropper color to the palette.
That should work. mail me if you get stuck, with your image
dimensions/copy of image.
