Paint for 9 year old child's bedroom

[ILiveInAmphibia]

Currently pale blue and feels quite cold. Also want something a little more grown up. So looking for neutral but warm and bright! Thanks

What colour furniture and does the child have a favourite colour ?

Furniture is white. If I ask him his favourite colour, he will reply 'rainbow' 😂

We took our 9yo to B&Q and let him pick himself from the sample cards. It's his room, his choice.

I did a warm medium light bright warm blue on 2 walls and 2 walls lightish lime green. Not sure if I’ve described it well but was lovely and had an ikea kallax unit with blue, yellow, green, aqua drona boxes.

Thank you! I did take him to B&Q in the end. He chose a bright yellow and a bright pink then I suggested a more neutral paint that had pinky tones and he was happy with it so that's what we went for! I'm not trying to be mean just would love it to be warm and calming - we will brighten it up with some pictures though and they can be whatever he likes
