Journal asked me to remove reference to colour in figure captions as this is inaccessible? There's _also_ a description of line/plotting character type. Seems stupid as my short-sightedness makes distinguishing by colour much easier than by e.g. line type
@DToher I think I settled on that. just seems stupid to object to additional description!!
@_jcken perhaps go with "the solid black line in the truth, the dotted red line is the estimate" as this emphasises the difference in the forms of the lines as well as the colours.
But who knows?
