You might have created the most esthetic figures for your last presentation with a beautiful colour scheme, but have you considered how these might look to someone with colourblindness? Around 5% of the gerneral population suffer from some kind of color vision deficiency, so making your figures more accessible is actually quite important! There are a range of online tools that can help you create figures that look great to everyone.

Colourblindness simulators are a useful tools to check how your figures would look to people with different types of colour vision deficiencies. There are many tools available online, I found that Pilestone (https://pilestone.co.uk/pages/color-blindness-simulator) is easy to use. The website allows you to upload your own figure and view it with a range of simulated colour vision deficiencies. Below you can see an example of my figure simulated with deuteranopia.

In case your figure does not pass the test, there are online tools available that can help you to create a colourblind friendly palette. I particularly like Coolors (https://coolors.co/) as it provides a nice interface to customise your own colour palette.
