Marks to create tone pattern and texture in colour

I selected coloured pencils  in the 3 primary colours 

Then Aquatone pencils and felt tips. I wondered whether the primary colours were blocking me so I used random colours for the felt tips.

I don't think these coloured versions are as good as my single colour ideas before but maybe I'm running out of ideas and need to do something different for a bit.

When I was using oil pastels I tried to clean one on an envelope and I think accidentally this might have been one of my best ideas!
