this is a huge issue for me because i do alot of photoshop work... i was laboring over an image in photoshop on my macbook pro for hours.... thought i had perfected the color. but when i went to view the same image on my brother's imac screen the color was COMPLETELY different. why is this? also even when i print an image from the imac, that image is a completely different color as well. is the printer the most accurate? why doesnt Apple just have a universal color system for all their computers i dont understand why one image on one apple system is different on another.
