problem with screen tinting... work machine

so I use a (I believe) 22" viewsonic crt at work… not sure on how old it is, but it doesnt look “too” old (maybe from late 90’s).

anyway, it seems that when something is displayed on the screen (a 3d model for example and the color of it is grey) it looks fine, but when I highlight it, it turns like a hot pink color(by default) but turns the window boarders a different shade of color than they normally are (even when a webpage background or an image is a certin color I get the same thing when it’s taking up a majority of the screen)

think the monitor is just on the way out?
