Well this post was entertaining! (6 pages in as many days!

)
There is nothing more amusing than having a discussion about a subjective topic - such as Color! And you're all Wrong! But you're also all Correct! Isn't that fun?
Apologies in advance for the breathiness of this response. I'm 56, an Architect and our firm designs Commerical, Resorts and Multifamily projects across the country (both market rate & 55+ communities) - and I deal with this on a daily basis. And over the years, I've seen the 'current trends' change from the browns of the 70's, to the muted mauves of the 80's to the long-living Beige Brigade to the recent 50-Shades of Gray! And that is exactly what they do - they change - based upon {wait for it}...
the {aggregate} people's tastes. These industries spend tons of hours and money into the research. It's no different in the Automobile or the RV Industries. The good news is it'll change in the Future to something else. Perhaps back to Mauve?
Notice I said 'aggregate' or the average. Specificity is relegated to the 'Custom' markets. Sure, you can get something in a very specific color or material, IF you're willing to spend a little extra. Now, regarding the OPs comments about 'them grays', well... I get it. it's not everyone's cup of tea. But then again, it 'is what it is' if that is what the companies are currently offering, and you're looking to purchase now - unless you can speak to them about modifications prior to fabrication. And that is speaking of the new coaches. Look at anything older, and you're going back in 'Taste Time'.
But again, this is all Subjective to you and
your preferences. As many of these posts eschew - what one person likes or prefers, another doesn't. But isn't that the beauty of getting/having an RV? You can get what
you like, what
you want - and what makes
you happy. At the end of the day,
that is what matters.
My wife and I had decided late last year to join this 'craziness' - and we bought an older Coach: a 2002 Holiday Rambler Scepter (a 40' diesel pusher). The interior is... dated, but in a well-maintained condition for being 21 years old. It is Green on the exterior with 'cream' flooring & walls, a white ceiling and natural maple (i.e bown) cabinetry, which is in good condition.
Our intent was always to remodel the inside- with the intent to be full-timers, travel and go see/do things. We plan to update the appliances, fixtures, new countertops & update the existing flooring (tile & carpet) to LVT or wood floors. Carpet? Who decided that was a great idea to put this in RVs? (Nevermind - that is a whole other 'subjective' topic unto itself.)
As for the interior color, remember I said I do this for a living? Yet even so, we spent hours looking at various paint chip colors. Hourrrrsssss. Technically any color is available - you just need to have them figure out the specific mixture! In the end... we intend to paint the walls a very light warm gray (i can hear the gasps now) - mainly with the intent to keep it as light as possible. Whites and creams were a no-go. Colors, while beautiful and nice were a bit too darkening. To be honest, there really is not a lot of wall surface when you get down to it. The windows, cabinets, & furniture take up most of the space.
Now here is where it's going to get fun - we also intend to paint over the maple cabinets. Yes, I can hear some of you fainting and uttering 'how could you?!'. Frankly because it is dated and while it is nice, it appears old. While I too am 'old', I don't necessarily want to be surrounded by reminders of that. (Don't worry, I am a perfectionist, so we'll do a great job!) We were leaning towards a light gray (but darker than the walls) for the uppers, with some specific accents we'll also add. Again this was to maintain the feeling of lightness & openness. As has been mentioned, darker colors have a tendency to make a space feel small and more enclosed. For the lowers however, we were leaning to a robust red, but a very particular shade. Or we might go with a rich, darker gray. Right now some of you are gasping for air. It's OK - I won't be doing that in
your coach.
Many bring up 'resale value'. And?
Our intention was to live in this, not to turn around and flip it. Perhaps if that
was our intention, we'd be doing things differently, but it isn't. I want to be happy where I'm living. The rest of the interior of the Coach will allow us to personalize it with other things. Colorful things.
And to finish, I think a lot of times that is why you see Industries like this endeavoring to keep things in a "Neutral state" - first with the browns, then with the creams, and now with the Grays. Acting as a backdrop and allowing your personal touches, your flourishes, your colorful knick-knacks to then come to the foreground - and display your wonderful personality.
You-be-You! And be the Best YOU, you can be!
See you on the road later this year!
