Yep exactly!
Heh so I ended up actually teaching a class on my birthday a couple weekends ago and mainly spent half the class getting everyone to think differently about colours - listing out all the positive and negative perceptions we have about each of the colours of the rainbow (as well as black and white).

Was so interesting seeing what everyone thinks about each colour and why we have negative feelings about some (like one almost hated orange, because she sat for months in a boring, soul-sapping office directly across from an orange wall!)

So I showed them how it doesn't have to hold those meanings for us if we don't want it to - we get to assign new meanings and feelings to those colours if we choose!
