Peopled have been saying that if you take notes on yellow paper with a red pen, it can help you recall the information better.
Compared to taking notes on college ruled paper with a black/blue pen.
Is this statement true?
No idea, but in my experience retention is better with handwritten notes than notes typed on screen.
Yellow is good for homework as it makes it easy to find it in the pile (if they still do that)
@bopper that might be a good idea as well.
