Not exactly. If you receive a PDF proof, your computer’s or device’s screen determines the colors you see in the PDF, and that’s not necessarily accurate. Colors vary from screen to screen because most screens are not calibrated. Also, your screen shows you colors in RGB (Red, Green, Blue), not CMYK, which in some cases looks very, very different from RGB. So your school colors might appear darker or lighter on screen than they will be when they print.

If you receive a color laser proof, that’s not accurate either because laser printers are not calibrated and are not high enough quality for color matching (plus the art will be reduced to fit, which can monkey with the colors). You’ll be able to see where the colors are, but not exactly what they’ll look like off the press.

If this is a concern, then see the previous question above for how to address color matching.
