Of course, they can! But not in the way they are supposed to.
For example, blue is a colour that calms me down, but it also gives me energy creativity, which makes me dream and spread very positive feelings in the end. However, they have named the saddest day of the year ‘Blue Monday’, which makes no sense!
I think each person has their approach to colour, and that’s why we are more receptive to specific artists or creatives because we connect with their approach to paint and the emotion they are trying to express.
I usually work with a reasonably small palette of colours as I make my glazes, and it is time-consuming and complicated to develop formulas that work well. I like that pieces can be combined, still maintaining a shared universe. At the same time, every season, I create new products and add new colours and patterns to keep them attractive for my customers and challenging for myself.
