(Q: the numbers with the owl heads, the wavelengths, do you want to reuse them at the end?)
MB : these figures appeared in the secret notebooks in previous versions with their unit the nanometer to indicate the color to the printer, they were in parentheses. The printer must have said he couldn't do something that precise so just the color without the number couldn't have been considered accurate. So it was decided to keep this color on the pictogram at the top of the page and to associate it with the number of nanom that accompanies it. Afterwards whether to use it or not he won't say.
