Hi all, been a while since I have painted anything but I recently felt the itch again and decided to finally do some Thousand Sons as their concept is by far my favourite.
Unfortunately, I find the bright blue and yellow colour scheme extremely gaudy and would like to put my own twist on the styling. I am currently thinking the majority of power armour should be a very dark/worn blue or indigo. The rimming on the armour would probably be more of a worn silvery-bronze while cloaks, cloth and other accent would be a tan colour of some description.
One of the other reasons I gravitate towards Thousand Sons is due to being a first-founding legion and as a result I would like them to look appropriately ancient (just ordered some Cataphractii terminators to help with that).
I have not painted minis for years though and I am unsure what paints/inks would be necessary for such an endeavor. I also see a lot of talk of washes - is this simply referring to extremely watered down paint to glaze over a model or are there specific pots I will need of that too?
Any other colour scheme input and specific paint recommendations/tips would be fantastic before I go and spend more money
Example ideas:

(I realise those are Night Lords but that is much closer to the shade of blue I am interested in.)

(This one is a bit different but an interesting idea.)
