I'm nearing completion of my observatory annex housing an ExploraDome on a 10x10 wooden structure. I'll be installing pre-primed wooden boards for the interior siding.

 

Question: what is a good color?  I'm thinking a dark, flat blue paint.  Any comments or other suggestions?

The inside is going to be dark anyway so any darkish color will work.  Do not use flat paint.  Its harder to clean and gets dirty easy.  Use semi-gloss.

Navy Blue or Midnight Blue sure makes me think of the starry sky.

Dark flat blue sounds good! White would be NG, but anything darkish is beneficial. I left mine just plain plywood with no two-layered wall cavities "so it can breathe", which naturally-darkens with time. That worked out well. The single layer of thickish plywood then the roofing etc. makes it easy notice and isolate any water incursion before it becomes catastrophic... And in the 30+ years its been operative, there was only one little leak, which I fixed nice and early. Ummm... the building also quickly cools down to ambient temp and humidity that way, without building up heat or moisture... why I call it ~breathing~ A building that's "too tight" invites heat and moisture problems. At least that's my theory.      Tom

I do a lot of work with the US Navy. So Navy blue it will be!  I won't go semi-gloss -- reflects lights -- but might do "pearl." Not that I ever expect to wipe down the walls.

My friend used flat, deep blue paint.  It looks nice.  Mine is medium brown, I'm going to change that.  My conclusion is wall color doesn't matter much, I keep the lights off when I observe anyway.

 

Now, my observatory is at a darkish site, not in town.  I might feel differently if my observatory was at home and I was battling street lights and light pollution.  I have been considering charcoal grey for my next coat of paint.  Either way, I'll use flat, and likely exterior paint to help make it dew-durable.

All I can say is thank goodness you are painting it. vs just leaving that raw unfinished particle board interior chic favored by so many.

Thanks to all for the suggestions. I've decided to use Downpour Blue from Benjamin Moore, in an eggshell finish.  I've used this paint before and like the colors. Nice rich dark blue.

Behr has a shade called Observatory (PPU13-19). Too light for me but they did not ask my opinion.

Behr must have an astronomer on staff. They also have "Intergalactic" Grey.

How much more black could it be? And the answer is none. None more black.

Paint companies drive us crazy having 147 shades of a color.

Where I work we occasionally evaluate colors, black is not always black.  For example, something that "appears" to be totally black in the visible spectrum can show up like a flash light in the IR spectrum.

 

So, sorry for the pun, but there at least 50 shades of black   smile.gif

With the weather in a proverbial lockup of POLAR VORTEX  and me stuck in the house  contemplating  what's next to do in my little sanctuary  of solitude ( observatory) .  I was walking aimlessly through one of the big box stores and came across

The black thin loop carpet used for boats,  this got me thinking of another member who covered his walls with carpeting.

 I bought enough to do just the walls for now , as I have carpeting and padding on the floor already ( grey) it's great to stand on for long periods of time and if you drop something ( eyepiece) it's less likely to get damaged. 

A couple of cans of spray adhesive  , box cutter and a few blades and I'm set.  Except now I have to wait again for the weather..  So my choice will be black.  

Another upgrade when it gets nice. Is a repaint of the dome, epoxy white this time, as the fiberglass  is getting to me a bit ratty in spots . So a good scrub, powerwash, then prime/ paint ...    

 Its 9 deg out with another 10in of the white stuff...   and not but one clear nite since dec 1.  .....

4.40 am time to shovel.......

Carpet would be nice, even on the floor, but that isn't practical here due to high humidity during the summer. We don't even have carpeting in the main house and that is air conditioned.

I've done both - painted a charcoal grey and left it bare.  I know black is the go-to color for many, but I'm liking the blue more and more.  A good coat of paint will make it easier to clean and provides a bit of protection for the walls. They make scrubbable flat and eggshell paints, and there are additives to make them scrubbable if you so desire.

 

I use charcoal colored indoor/outdoor carpet from Lowe's on the ground.  It will last a few years, and is easy to replace when the moisture/humidity gets to it.

Eggshell is a good choice...non-reflective for the most part, like flat, but wipes clean like the glossier shades.  I use it everywhere inside my house.

Dark Blue is a great colour for observatory walls. I couldn't help myself and just went traditional black, with charcoal marine carpet on the floor.
