Sometimes you will refer to "yellow" tips and "blue" tips in quotes. Why is that?

Originally, all 200μL pipette tips were coloyellow, and all 1,000μL tips were coloblue. People would refer to them by their colors, as it was easier than specifying the size. Later it was determined that some of the dyes used to color the tips could interfere with their work. So colorless versions were developed of the tips, but often they were still called "yellow" or "blue" even though the tips were no longer colored. BRAND tips, when purchased bulk are colofor easier identification, but are free of cadmium dyes, which was the most problematic. BRAND tips, when purchased in racks are colorless to ensure no problems. The plates on which the tips are inserted are coloyellow, blue, dark gray or green for easy identification. The dark gray carrier plates indicate our special nano-cap™ ultramicro tips, and green indicates our 300μL tips. Boxes of ultramicro tips have colorless carrier plates.
