Show possible colour combinations.

I hope this is in the right place and that it's OK to post this kind of question.

I'm making a blanket using 7 colours to make many squares which will be sewn together.
Each square uses 3 colours, in a concentric ring pattern kind of like a bullseye. I want to use every possible combination of these 7 colours in this ring pattern. Order in the ring matters so:
'Pink, blue, yellow' and 'yellow pink blue' would both count as different combinations of the colours.
It's been a while since I did any of this kind of maths but I think there will be 210 possible combinations in total.

OK so my question is, is there a way to get excel to tell me all of the possible combinations/ orders of the 3 colours. So I would have a kind of list I could tick off when I'd used one.
I know this sounds like a pretty trivial problem but I've become really interested in the maths behind this project. I'd really appreciate any help or hints.
Thanks.

Maybe this:

That's almost it. I should have said each colour can be used only once in each combination. I can just ignore the ones with repeats though.
Thank you so much
