I am a teacher -- I send many notes home with my students. This bright colored paper is what I use! Notes don't get lost--they get noticed! I also use this paper to run off any special papers the students might need to "hang on to" for the quarter semester or year! It is easy to find and it is also easy to see if it happens to get "accidentally" recycled!
I bought the color paper for my students to make foldables. The colored paper is nice but too expensive. I can only afford when it is on sale. I would love the pastel colored paper. However they are never on sale.
