I have adequate amount of understanding (I think) about non-cadmium red color family, and also I get a little tired of painting individual red roses. I mean the result was not bad, but I felt I became a sort of handicapped in painting after I started to develop my non-toxic palette. Many skills I used to have are no longer working any more. It just like our physical body. We take it for granted until we get into a injury. I must be patient during this healing time. I use to be so picky about the difference between oil primed and acrylic primed painting surfaces. Now I just laugh, and let it go.
