Coloured diffraction spikes

I chose an RC design scope (GSO RC8) as I felt it was a less expensive option than a high end refractor in avoiding aberrations such as chromatic. I have just run my first few images and notice that the diffraction spikes show colour.
My understanding is that the RC design provides a refraction free path and I wonder is the colouring a normal artifact of spike diffraction or something unusual.
