I recently made the mistake of creating a starry galaxy mural on my eldest daughter's bedroom wall. This was very straightforward and involved only some dark blue emulsion (which I had leftover from our cloakroom) and some star decals I bought on Amazon. Unfortunately, my youngest daughter saw this and took it as an invitation to ask for something more involved for her bedroom...

So I'm now tasked with painting a rainbow on her wall (4m wide and 2.35m tall). The actual artistic piece is fine but the piece I am struggling with is where to buy smallish quantities of ROYGBIV paint. I don't want to buy 2.5L pots and have huge amounts leftover (which I will never use) and I don't think tester pots will be large enough.

So... Is there anywhere I can get 500ml tins of normal emulsion for walls? I've looked in the usual places and am coming up short.

TLDR: Where do I buy rainbow paints in small quantities to keep my 6 year old daughter happy?

Your heart set on emulsion?

TBH I'd use spray cans for this or alternatively art paint, you can get ready mixed colours for about £2 for 300ml (iirc) in hobby shops; white base layer then paint over, jobs a good 'un.

I woudnt get too hung up on it being wall paint.

Matt waterbased wood paint, for skirting boards etc is going to be just fine, if you can get a dec shop to tint you some undercoat even better.

Or tester pots, or spray paint as above.

Test pots at B&Q usually do the job.

No not set on emulsion - I had just assumed that would be the best option. Art paint is a good shout!

I presume that now you can get tartan paint, then rainbow paint would be as easy to get hold of! biggrin

I bet you can buy wall art that just sticks to the wall and comes off easy if you want to move it or get rid at the end

We had one of a tree with animals and birds years ago -- it was great - got moved a few times for wall colour changes and never left any marks

Wasnt expensive either

It's not quite 500ml but you can buy 1l pots from B&Q.

You can (we also had the tree at an old house) but they tend to be a little smaller. The room is quite large (this is the smaller wall) and so I want to do a big one

If it helps you only really need 3 of the tins of paint to mix them all to make the rest biggrin

To follow on from Mr Pointy -

Here's just one of Amazon's solutions.

Lots of choice.

My daughter bought a huge rainbow sticker for her kids bedroom, came in 4 bits so easy-ish to put up, designed to take up a large wall.

That's clever - and a good art/physics lesson for her too!

Johnstones sample tins are 350ml and <5 quid a go. They'll mix any colour.
