First of all, all LVT/LVP can be damaged by sun - it color-shifts. Regardless of brand, btw, unless a mfg has come out with a High UV-resistant line post-2015 when we did our LVP in the MBR. However, I can say that it does take a consider amount of sun to make the difference, and I live in Northern CA where with an East-facing exposure, there is direct sun on my entire 2003 LVT kitchen flooring pretty much 300 days/yr. Knowing this, I had window film put on the main windows, but it only cuts it 50% (the 100%-UV blocking clear film wasn't on the market back then). There has been a very slight color-shift on the LVT over 14 yrs, which I only noticed because one tile had to be replaced in 2016. Now, the pattern on my LVT is a slate-look, so it's less noticeable than a wood plank. The new replacement tile is a touch darker, and a little more reddish-tinted. Realistically? It can only be noticed if you stand right over the tiles and look at them. From the usual side angle - say, you are 3' away and looking at it - you can't tell any difference. So...will a wood-look LVP see a color shift? Possibly/probably. Have your windows anti-UV filmed - it wasn't that expensive, when I had it done in 2003 - and that should pretty much take care of it. We have the Mannington Adura Essex Oak in our MBR which was installed in 2015. It's glue-down, our installer refuses to do any other type of install. We're extremely happy with it so far. Our south-facing windows downstairs are uncoated, but we always keep those blinds closed since the only view is of our neighbor's house! If I had a view off to those side windows I would have just had them filmed. The other large window is north-facing, and indirect sun is not a problem. High UV can damage just about anything. Before I had our kitchen windows filmed, the sun, over a decade's time, managed to fade even the laminate sides of my cabs, and laminate has the highest UV resistance of ALL materials. The UV actually bleached out the beech wood trim on the doors, turning it white in a few areas.

@littlebug - I appricate your feedback, since I am open to others ideas. What color would you suggest? I do like the Scandinavian style, so I might be going with a lighter floor. Here are a couple of examples of brown furniture with gray walls, I find the look harmonious and pretty!

thank you for the replies. sorry I wasn't very clear. we are taking out all existing flooring. Want to replace with lvp (wood) everywhere except kitchen and guest bath. considering lvt (tile look) for kitchen and bath. this is picture of cabinets etc in kitchen. and living room. walls are different color now. shades of green koi pond and a darker green for accent. would like to stay light to med on the lvp wood for flooring. nothing too dark and will blend door, cabinets etc. don't really want wood look in kitchen as I think it will be too much with cabinets, thus considering a lvt light in color .. I hope this helps explain my dilemma.

Plot twist- Our youngest child has been struggling with allergies. Yesterday, her Dr suggested it is most likely the carpet. This is a new issue as our last space had carpet but she never struggled to this point. The children currently sleep in a triple bunk bed and she sleeps closest to floor. We had a few estimates done to replace carpet for upstairs bedrooms (3) all came out to over $1000. (One company flat out told us the carpet was newer but poor quality, not properly cared for & he could tell pets were an issue.) We ended up deciding on Waterproof laminate Flooring from a local flooring liquidation store. We will be using it on the entire third floor. We were able to secure a medium grade wood look with underlayment. We also purchased underlayment to help with noise reduction. I kiltzed/treated the subfloor and it has been airing out. We purchased a open box floor cutter and spent a total of $498 for the Entire floor . and supplies. (My husbands military discount really helped) We plan to install ourselves. I know it's not many people's first choice but, it seems to be the best financial option for us at this time. I will attach photos of the flooring. Instead of sulking I am thrilled our children will have clean flooring and am looking into some reasonable area rugs. We are using some of the money we saved on flooring to head start our upstairs flooring fund & a portion to buy the kids warm area rugs & bedroom shoes. :) Thank you all for your valuable feedback, my husband now asks me lol “What did your internet friends say?”
