Currently, I'm investigating the effect bedroom color has on one's quality of sleep. Many (non scholarly) works I've come across have mentioned / cited this survey, conducted by Travelodge in 2013. Looking into it myself, it appears to have little to no scientific foundation. Can someone please verify whether or not this survey is valid? Are there any other studies that I should take a look at?
Survey:
THE SECRET TO A GOOD NIGHT'S SLUMBER IS TO SLEEP IN A BLUE BEDROOM

Dear Megan,
The first evidence relating blue to a good night’s sleep come directly from the Tavelodge survey itself because they ask all their visitors for their estimated hours of good sleep and they have correlated their answers with known bedroom décor. The resulting database then allows them to rank blue decoration highly for use in bedrooms.
The work by the Swiss scientist Max Luscher on emotional colour-meaning, tends to support the significance of Blue in this context. He found using word association experiments that the most common terms related to Blue are “Depth of Feeling” passive, concentric, tranquility, calm, and tenderness.
Dear Megan,
the Travelodge survey does indeed hold limited scientific merit in my opinion. In my research I have come across this study multiple times: "Effect of illuminance and color temperature on lowering of physiological activity" by Noguchi & Sakaguchi, 1999.
They come to the same conclusion as Travelodge: Low color temperature light might contribute to a lowering of CNS activity and might thus be helpful in the bedroom.
