Phal leaves purple, maybe turning yellow?

[MiffyThePhalaenopsis]

Hello, so I recently changed my orchid's placement since I'm really forgetful and putting her next to me has helped remind me to take care of her. She seems to have been doing better since I've put her in my room, but lately I noticed some colour changes in the leaves, notably in the centre where it looks light green and purple, and the bottom of the bottom leaf is very much purple. Her leaves look nice and dark green with no yellowing on the edges. I don't know if this is a cause for concern with the centre of her leaves to be changing colour or not.

The newest leaf, which I took a pic of the underside of, seems to be thinner than the others and hasn't really gotten thicker for a while. When I first got her, she had magenta flowers, but she hasn't really sprouted another spike since her last flowers died off.

She sits at a north-facing window, but my dad said that the windows block out most UV rays. I figured that it would be fine since it's currently winter and there's not really much sun. Her leaves don't feel hot in the afternoon either, so I don't really know if it's sunburn or not.

Don't mind the string by they way, she usually hangs around in her pot most of the time.

It looks quite ok. As long as the orchid gets gradually conditioned for higher light levels ----- then should be ok. Maintain suitable growing temperature for the leaves and roots.

And also mention roughly how long this orchid was has been growing in the new growing area. Eg..... 3 days? 1 week?

Many Phals have purplish pigmentation and leaf mottling, especially with higher light levels.

It's been about a week and a half or so. I started with the blinds horizontal so it wasn't fully hit, and now with the blinds up throughout the day.

That Phal looks very good. New leaves often feel a bit soft, and they also tend to color up more easily than mature leaves when exposed to higher light. Phals with pink/purple flowers also tend to have more visible purple to them as well.
