Hello, I hope you can help me with this issue since I could not find an apropriate solution so far. For my report I am not allowed to use diagrams with colors which are not recognisable after a black/white copy anymore, like the one attached to this message. Since a normal greyscale of the attached plot makes blue (lowest value) and red (highes value) looking similar. This is not an option. I am seeking for a quick way to, let's say translate from a color range (blue to red) to a grey scale (white to black). Since I have to do this for several images I would appreciate a quick way, if there is one...
I heard that there are more than one weighting algorithms like (R+G+B)/2 or 0,3*R+0,7*B+0,11*G and so on, but basically I would be interested in 0*Blue + maybe 30*Green + 70*Red to achieve White as a minimum (which is now marked with blue color) and black as a maximum (which is now marked with red). Thank you in anticipation. Best regards.
