We are just doing our staircase and we have LVP and are using it for the stairs to match the flooring. I never like real wood and fake next to each other

If you have completely exhausted other options, I think this choice will be fine.

We recently redid ours (with similar issue) and don‘t even notice, as we added a runner in the hallway and that helped draw the eye away from the slight difference.

Sorry but this is too obvious to me. I see plenty of green in the vinyl (brown with green and gray tones) while I see plenty of orange/red. Some people have a hard time seeing undertones. It takes a trained eye that does not have any colour-blindness concerns (up to 30% of men have some form of colour blindness...which could explain some things).

The treads are too close to a 'bad match' to make this work. I'm sorry but you would be better off gluing down vinyl on the treads and then figuring out a nosing.

BTW: have you measured everything to ensure your stairs will maintain 'code'?

Once a stair changes finish (like carpet to hardwood, vinyl, laminate, etc) the stairs must be reassessed to ensure code compliance. A finishing carpenter is the person needed to make sure stairs remain to code.

The top of the stairs and the bottom of the stairs are where you would see issues when changing finishes.

If you paint the riser white instead of staining it that would cause a visual break in between the two wood tones and make any small variation less noticeable.

Hello, would you mind letting me know how your staircase project came out. I'm considering using the same product for basement stairs
Thank you,
