A long time ago I saw this quilter on tv. I can't recall her name but they went to her house and it was an explosion of color, a la Kaffe Fassett. Anyway, she said that she considered red a neutral color. She said that you could choose a group of colors that went together and add red and it would work.
I tried this concept with the Peace gloves. I chose a bunch of pastels and added red. The scanner isn't getting the red right - it is much darker in real life and there is a little more contrast in the colorwork on the cuff. I initially did the fingers in each of the pastels but it looked awful so I'm redoing them in red. I'll get better photos when I'm finished. I think these gloves will match my embroidered denim jacket quite well.
