They may vary from monitor to monitor (depending on the quality and your personal settings) and may not match actual dyed fabrics. Some colors can shift dramatically on proteins such as silk and wool (for example, black gives a lovely maroon or brown). Colors can shift due to water conditions, temperature, etc., and dyelots can vary sometimes. When your end color needs to be very specific, we recommend a test first, before dyeing your main project or going into production. All of the colors can be mixed for an endless pallet!
