The insulator on the left is a bit darker than the one shown on the right of the previous photo. It also has some milkiness which is not visible. The "braille" on the right is royal purple and as dark as we believe they come in. I will show a daylight-lit window-sill sill line-up of these in the near future so that you can capture and appreciate the full beauty of these very neat Canadian insulators. They are my favorites!
