My card collection is pretty much just sitting on my floor in piles of colour. I make so many different decks that it's inconvenient for me to have them stored in any way. Just quick access to anything i need on the floor <3

If you're just starting I would recommend going for a mono coloured deck as your first venture into deck building, and then once you've had a bit of time to get use to it you can introduce a second colour, or a third if you're that confident.
I personally have yet to get to the point where i feel like i could pull off making a 3 coloured deck. that's with 2-3 months of regular play Dx
