I must admit that these colours do not go with the season we have - winter. These are autumnal colours. However I felt attracted to these colours, so I used them. This time I took a separate piece of cardboard and swatched the colours I wanted to use. And voilĂ , I noticed that I have quite a broad range of yellow hues. I actually had forgotten that I owned that many yellow markers. So there is no need to buy any of that colour range.
Another thing I learnt was that I could produce some very nice dark colours by laying green over red.
