Tide graph experiment: seeking a colorblind friendly palette

This is a first try.  I am working on a graph of height of tide as a function of (x) clock time.

This time, I have used the "Juxtapose" web tool to compare a graph (work in progress) with a simulation in The Gimp of what this image would or might look like to a person who is somewhat  colorblind with Deuteranomaly (apparently weak green vision).  For this simulation I have used the Color Vision Deficiency python plugin for the Gimp.
We can be pretty sure that these figures do not look like this to colorblind people; but I can see that my intense, contrasting color palette does not work to discriminate the different lines for persons with color deficient vision.

The color deficit is Deuteranomaly weak green. Pull the slider to the right to see the original image; slide to the left to see the simulation of what we may think a person with this deficit in color vision might see.
Scroll further down to see another type of colorblindness.
The objective will be to produce colorblind-friendly graphs. I found this on the blog of the website with the slider maker: https://knightlab.northwestern.edu/2016/07/18/three-tools-to-help-you-make-colorblind-friendly-graphics/index.html
