colour pinhole photography

I have decided to take my black and white pinhole photography to another level and started to work with colour paper instead. I have just developed my first two prints, each holds an orange glow, with one sharp spot of green. I like how they still hold the same ghostly qualities of a black and white pinhole photograph yet have varying hues of colour. From my research into colour paper I think different types of colour paper hold varying hues of colour, for example some will process with a blue hue instead of orange. However, I would like to try using colour filters over the front of my pinhole to see what effect this would have on the image, can I create another hue?
