Joshua Jackson painted a "rainbow room" for his daughter to cheer her up after they lost their home in the California wildfires

In a post on Instagram, he shared a picture of his girl's new room and explained: "Last month I posted a story about our house burning down. First I want to say thank you to everyone who reached out and kept reaching out, it means so much during these times.

"I also wanted to put an update here, something a little more positive. For months before the fire JR [Juno] was on me to paint a rainbow room. I was working and I couldn't quite figure out where to do it and yadda yadda ...

"I didn't do it. Which I now really regret. So what you are seeing here is the newly unveiled rainbow room (huge thanks to my landlords for not batting an eye when I asked them if I could paint their walls 'rainbow').

"Because while I can't give her a new house(yet) we can certainly have some rainbows along the way. We're doing alright ... to be continued."

Joshua also recounted a conversation between him and his daughter about her specifications for her rainbow room, writing: "JR: Daddy when we build the new house we should have a rainbow room. Daddy: I got you kiddo ... JR: With a blue sky roof. Daddy: I got you ki... [sic]

"JR: And pink. There needs to be pink. Daddy: ... Yes ma'am."

It comes after the former 'Dawson's Creek' star admitted he's having a "hard" time rebuilding his $2m home in Topanga Canyon after the wildfires.

He told US TV show 'Extra': "I'm just at the very beginning of it, so it is going to be a process, but I have my plans in with L.A. County and hopefully they turn those around pretty quickly and we can get into the building phase.

"It's hard, and a lot of people are going through it and everybody's going through it in their own way.

"For me, there was no question of rebuilding, and I want to build a place for me and my daughter that will still, quick enough that it will still be her childhood home, so I'm just on it, trying to push my way through."
