With our Natural Dye Kit, you can dye items in shades of pink, yellow, purple and orange.  However, if your water is hard, or very alkaline, your cochineal samples may come out more purple than pink.  To make sure that your colour is red/pink, add a glug of vinegar or the juice from a lemon or lime with the ground insects when you first make your extract.
For the green, you need to take one of your pieces of yellow dyed fabric, and overdye it in the indigo vat.  The yellow plus the blue will make green.
