Editing colors in a colormap

In my code, I'm using the imagesc function to create a changing colormap as a movie. I have created a manual map that goes from the white to black scale. However, there are certain parts of the colormap that I would like to manually make a color that does not fall in the white to black range, such as blue. I need to do this within my code, so that the code can capture the image as a frame. How would I accomplish this?
Thank you.

How do you have your colourmap currently? If you have it as an e.g. 256x3 matrix of colours then you can just set e.g.
myColourmap( 100,: ) = [0 0 1];
to make the 100th index colour blue.
