And the reason, I'd imagine, is in the heat of combat, you need some ammo from your buddy, that you know where he's packed it and can get to it without asking. And the sooner you enforce this discipline, the better off you are.
The same goes for PI ProcessBook displays. The great thing about ProcessBook display is that once you know how to create stuff, people go crazy and create a bunch of displays using the default colors. There are some folks who will change their own colors, but overall, it's a jungle out there.
The bad part of this is that displays are usually shared. The way people actually use ProcessBook is by pulling it up to show someone.
Maybe you're a Manufacturing Sciences plant support guy and you need to show an operator what's going on and why he needs to switch to controlling off the other probe.
Maybe you're showing your boss why you think this batch of media is contaminated.
Maybe you're presenting data to the VP of the plant a real-time status update and you needed a screenshot for your Powerpoint presentation.
Whatever the case, the moment you show someone your ProcessBook display, they're spending the next 5 to 10 seconds reading the labels to figure out what is going on. Meanwhile, you've started explaining what's going on, dragging that cursor left and right.
The way to fix that is standardizing on your colors:
For cell culture displays, I've proposed:
- pH and related trends - red
- dO2, Air, O2 Sparge - blue
- Temperature (Vessel/Jacket) - green
Red and blue represent hot and cold, so a neutral color like green makes sense.
- Agitation - black
- Volume - orange
The color of media is orange
- Pressure - grey
