I prefer shadow puppets...
I have no idea how many OH Projector slides I have prepared. A lot of work in the day, before color copier ready sheets.
And just to show how tough I had it, Preparing DD forms on mimeo sheets to save the Government money printing them.
Back in the day, when we had to hand carve our briefing slides out of clay and bake them in the sun ourselves, I went to squadron officers school at Maxwell AFB. They had a large lecture hall painted light blue. It was known to all students and alumni as the “blue bedroom.“ Caught many a Z there.

And blue is a bad color for a room to keep people awake in.
The Navy spent $$$$ on figuring out colors for submarine interiors.
Red and Blue were both BAD.
Of course, you dealt with the colors of a sub more than regular people deal with a room.
So what color is good?
500 different shades of grey.
a few shades of white.
Some greens.
Lighter shades tend to be preferred over darker shades.
Blues tend to cause more sleepiness, or inattention.
Reds tend to increase the number of fights between crewmembers.
50 Shades of Grey? In a submarine?
Yep.... Navy Seamen.....

And painting them purple makes sleepy sailors fight one another.
