Don't be afraid of using a dark colour on the walls, as long as not every wall is dark (as suggested by Dytecture the room will not close in. Keep your bedding a light colour for contrast. The larger windows could be treated with curtains/sheers as this would make a great seating area for a wingback chair and small table for reading etc. The other windows could be covered with a vertical treatment to help lift up the ceiling. I might suggest interior faux wood white (or wood grain) shutters or similar curtains to the other windows but hemmed to fit the size of the window (no hanging to the floor on the smaller windows). The headboard of the bed on the lowest wall with a low headboard to fit under the window would work or if there is no doorway on the right wall (foot of the bed facing the short wall with the two windows) a larger headboard would work there. Update the light to a chandeliar or drum light fixture. Good luck.

You can research seal failure to learn more about what can cause it. Good window film manufacturers are confident in the quality of the product when properly installed to cover warranties that window manufacturers void when film is installed. I have not seen a $500 deductible from a window film manufacturer warranty but you should always get a warranty in writing. Happy to send you a copy of ours if you send me an email. Many building professionals are uninformed on the latest technology in the window film industry. Millions of windows have film applied each year without incident. I can share horror stories of seal failure in homes less than a year old with no film installed and success stories of window film that has been on windows for 15+ years that still looks new. When the proper film is professionally installed you will be covered under warranty and will drastically improve the performance of your existing windows while keeping your view. Improper applications installed poorly will likely have problems just like a poorly installed roof is likely to leak.

That is a good idea as the sun's reflection can cause a lot of stress on any plantings that might be along the wall. When we bought our home the block wall was white which was not good so we ended up having it painted a medium-ish beige and that color absorbs more of the heat. However over time the color has faded and is showing an almost pinkish hue. So it's now time to paint again and I am in the process of picking a color myself. It really is up to you as to what color you want. I would look on houzz photos and search exterior wall colors and see if anything pops up that you like. Also, just head to your local paint store and start looking a paint chips. You can purchase a few sample colors as well.
