Choosing the Right Colors for My Needs
Colored index cards come in a variety of shades. I pick colors based on how I plan to organize my information—bright colors for urgent tasks, softer tones for general notes, or multiple colors for different subjects. Having a good assortment helps me quickly identify categories at a glance.

Additional Features I Look For
Sometimes I need index cards that are lined or have grids to keep my writing straight, so I look for those options. Perforated cards or those with pre-punched holes can also be handy if I want to organize them in binders or flip files.
