my guess of the sentence : "I" want to dye or change the color of our blue badges so as to getting into the balcony, but since we are easy to be noticed so I gave up the idea. if my guess is right (or not), then "to color a different shade" meaning to "dye or color it"?? why the word "shade" used here? what does "shade" have to do with color? why not just say "change the color of our blue badges" or just "color it"?
here is the sentence:
They wore little badges on red thread, marking them out as special. I wondered briefly if it was possible to colour our blue ones a different shade, but decided that being the only people with a wheelchair would probably make us a little conspicuous.
here is the context:
"they" are someone in the balcony, wearing red premier badges, while "we" are wearing blue badges on the stands watching races in the rain, freezing cold.
