plotting a series of lines with specified colours

Hi,

I am trying to plot a series of lines on a single plot in Matlab2018. I have specified the colours correctly and checked that my data variabes are correct. For some reason I cannot get matlab to plot my data using only the colours I have specified. I have 5 colours - blue, light blue, green, yellow and red (blue = fast velocity and red = slow velocity) and I have two sets of data to be plotted for each colour. You will see in the legend for the image I am producing, that there are other colours being used e.g. purple and that green, for example, hasn't been plotted twice. I do not know how to correct for this and ensure that the plot follows the order I have specified in my code (please see below)

Many Thanks

P

Hi Stephen Thank you so much - was over complicating the problem instead of making it simpler.

Many thanks again!
