Oh, man. This is all making me so sad. The whole reason we got two new sun tubes in the living room was to pull in full spectrum light, but now I find that in order to counter the blue cast from these things, I might have to add more cast. What I will say is that if your have the 14" sun tunnels from Velux, they sell a "neutral light" filter that is spec'd at around 3600K, so, not sure how that compares to using a theater gel, but it might work for some people, and you don't have to cut it yourself. For my purposes, I am going to have to do some other experimenting, because I need more of the spectrum, not less of it (for me to do artwork, but also my plants). If anyone has been able to track down the source of the bluing (is it the diffuser, or the inside of the tube, or possibly the dome on top?), that would be a huge help. Of course, I will check for the blue film! Thank you all! Addendum: I just took the diffuser out and looked at the light coming in, and it is definitely not the diffuser causing the bluing, nor is there a film in there. It's the top dome I think. I conveniently have an older sun tube in my bathroom that does not do the bluing thing, and it also does not have a tinted dome on top, so that seems like the main difference between them. Now I am wondering if the dome can be replaced maybe with something not tinted...

"ashes the contractor to remove all if this. So how the mirror tiles are installed correctly?" "I did but didn’t pay attention to this" They appear exactly how I would expect mirror tile to look. You did not do your due diligence and know what you hired him to do, not his fault. Pay him to tear it out and reinstall what you want. Unfair to expect him to do it for nothing because you did not understand what you asked him to do.

It’s blue/violet in the morning and evening yet perfect midday. I'm so sorry you're having a meltdown - super frustrating. But this is a great example that disproves the ideology that undertones are an attribute of color. Undertones are just someone's subjective opinion of what a color looks like - to them - under whatever kind of light source, in some random context. Which is why there is inconsistency about what undertones Reflection is suppose to have - or not have. If undertones were indeed a repeatable attribute of color and not an unfortunate ideology that totally ignores the factor that light plays, then there wouldn't be any confusion about what a color is or isn't suppose to look like. The color would consistently show up with the prescribed undertone, all day every day according to everyone you ask. But there isn't consistency with the undertones theory. The truth is Reflection factually, objectively belongs to the Green hue family. We know that because we can measure color, capture it's data and use that data to make, manage and specify paint colors. Having data means we can track and - to a great extent - predict color appearance. Because of the data, we know near neutrals, like Reflection, that belong to the Green hue family can shift bluish-gray in certain lighting conditions; slipping into moments of lavender or periwinkle isn't much of a stretch. If a near neutral from the Green hue family flashes bluish/purplish, the likely cause is at times the inherent light is heavy in the blue to violet limit end of the visible spectrum of light. Which is why it looks perfect midday and blue/violet morning and evening. Measuring color and organizing it by hue family accounts for shifts in quality of light. Assigning rigid undertone labels doesn't.

I have a mirror addiction. Placement is key. There are no steadfast rules. I think it is more about how you are reflecting the light or architectural interest of the room. Can the mirror hang on the west wall to the right of the door? If so, it will reflect the light coming in the window and the view out of the window. It will almost serve as a second window. Hanging it above the sofa just reflects the flat wall across from it, which doesn't really add much to the space. I think it is fine to start with a piece of artwork or a mirror as the first item in a room around which to anchor your other furnishings. The layout of the space does look like an uncomfortable waiting room. Who is going to be using this room and when? Is it an additional sitting room or your main living room? Are you wed to this furniture or would you consider swapping the love seat for an arm chair or two?
