What do we think about using un-natural colours?

During my most recent drawing class we had the lights low and a spotlight on the model, I hadn't realised how pink this pencil was until the main lights came up. I like it though...thoughts?

I love it tbh, I feel like sometimes using unnatural colours can get the creativity flowing, even if you're still just drawing with a pencil.

I think it’s a creative way to draw from a personalized perspective .and it can reflect stronger emotions

Unnatural colours can heighten the contrast, which makes the light and shadows more dynamic imo, and none-natural colours also add stylizing elements which can make the drawing more appealing :0

I'm a big fan  - you can see in my sketchbook I have a whole lot of doodles in cyan! :)

My whole sketch book is in unnatural coloured pencils it gives a fun contrast between the figures and the lighting also it doesn't smudge around like pencil does

I love it! It helps to add interest and variety, breaking the monotony from using one particular medium.
