Viridis Spectrograms

Viridis is a colour scale designed to meaningfully represent quantitative data and to be perceived clearly by everybody including those with colour blindness. It provides a perceptually uniform scale in both colour and greyscale. Using a viridis colour palette generator, I applied the palette to the spectrogram visualiser in my music player, Foobar2000. It seems to work well. It makes a nice change from  rainbow colours but still has a wide range of hues, picking out features in the images. Each image shows 30–35 seconds.
