Help - lightbulbs to reduce yellow light/walls

[Fortuny]

I've just had a room painted in what I thought was neutral and there's a definite yellow tinge, especially at night.

I've found these bulbs pictured below that claim to filter out yellow light, reviews are brilliant, but they're USA only.

Is there a UK equivalent bulb? Would any daylight bulb work? I've always found them quite harsh.

I am not sure how a bulb would filter light? I assume it means it is towards the cooler end of the lighting spectrum with less/no yellow and so would be like a daylight bulb. I found a pic which shows the Kelvin scale which is used to show how yellow the light from a bulb is. It might say in the description what Kelvin that bulb is and you can find a similar number in the UK.

I would try a daylight bulb and see what you think? Definitely cheaper than repainting the room.

Thanks @Geneticsbunny great idea
