Thanks Sumaiya.
However, I think that I didn't make myself clear when I asked the question about your Vectorstock image ... When I said: 'do you have an interpretation?', I was referring to the specific image - the one of the Ishihara color-blind chart.
Because I myself am color blind, I can't see numbers on the chart, but I know that there will be an interpretation of these numbers (for folks like me!).
Can you help me now? Perhaps you can tell me what numbers YOU see.
Sorry to be such a nuisance,
Fred
