I think the only effective way to do something like this is for the shades to be similar. This is a bright, bright yellow and a pale teal. The accessories are one option. I think if you made the yellow a paler yellow (similar shade to teal) or the teal stronger (similar to strength of yellow) you'd be better off. Then you could add an element -- perhaps pillows that had both colors--or even paint a stripe or other accent shape on one wall incorporating the color on the other wall. Perhaps a zig zag line one one wall with the other color (but only after finding shades that work together). To my eyes, these two shades do not work well together. Another option would be to make it floral in some way (If you insist on these two shades) -- you could add some pale flowers/greenery to the yellow wall and some bright flowers to the pale wall. I am not sure if that would work but in my mind's eye it does - in a funky way. If I did that I would also add uplifting sayings to the wall.

No deglosser....not something floors get. I could search the internet for this Dura-Wood product, but the finish should be listed on the boxes. If this is a "standard" polyurethane/urethane finish, you can do a "buff and coat" to add a lower gloss "satin" finish to the floor. I don't recommend this because LL has been known to have issues throughout their product lines. A full sand and refinish would be a better option to reduce the gloss. A professional installer would then add a depth of stain that is consistant throughout (both are hickory so we should get a decent result..."should" be the operative word with LL). If this is an Aluminum Oxide finish...simply enjoy your floor and deal with the "towel dry" option. Smudges occur on dark flooring. Streaks occur on dark flooring. Streaks/smudges occur on "shiny" flooring. An AO finish is one of the toughest finishes to do anything with...even professionals shake their heads and walk away...telling you it would be cheaper to remove, reinistall and refinish with a site finish. A traditional site-finished floor can receive a 'buff and coat' (light sanding with a new coat of finish on the floor without going down to raw wood) to change the gloss. Factory finished products are much more difficult to deal with because factory finishes are "different" than what is used on a site. Check the box to find out what type of finish you have (UV cured poly; UV cured urethane; 7-9 coats of UV cured Aluminum Oxide urethane finish, etc). Make your decision from there.

I don't, but you may want to go back to the product you found and post the question on that page.
