Well yes you can get colour photos from a mono camera, narrowband as well, BUT you need colour and/or narrowband filters to produce images that can be layered together to build a composite colour image. For example if you want a colour image of the Lagoon Nebula you would need to shoot red, green, and blue filter images to produce a composite. A One Shot Colour camera, like the ZWO ASI 1600 colour will produce a single composite image because it shoots all three colours simultaneously. The down side of One Shot Colour is the loss of resolution compared to shooting a colour in mono, because the colour camera uses a Bayer Matrix that is effectively a pixel colour filter so that some are red, some are green and some are blue. I always suggest any beginner should start with a dslr colour camera to 'learn tge ropes'. You need to understand image capture techniques, stacking, processing, etc, there is a learning curve.
