Here's why you don't need a separate legend for every colour in a scientific poster.
One of our former students, Mihaela Bejenari from Aalborg University, shows how to do it. She introduces her colour coding right at the visual entry point: red fluorescent protein, green fluorescent protein, named and coloured in the top right, close to the title.
So when you reach the results graph or the microscopy images further down, you already know what the colours mean. Which is great, as you won't need to hunt for the legend.
Another smart move: she avoids pure red and green, shifting both hues slightly to make the combination more accessible for people with colour-vision deficiencies.
These are small design choices that really add value to understanding. So if you thought an entry point is only there to grab attention, I hope this convinces you otherwise. Mihaela shows in her poster how it also gives the reader the context they need to understand everything that follows, including the hard data.
