On one hand, I died a little at the kaleidoscope of neutrals that my mother thrust into my hands this morning with a desperate, "I trust you to pick a wall color for me."
On the other, I can distinguish nuance in color very well, and quickly discarded 99% of the samples with the reasonings why (wrong color temperature, too close to the couch's beige, poor base tone given other items in the room, etc.)
Sadly, I was not able to convince her to go with a red sampled from the couch swatch on the table (she's done red in the past from my advice and loved it). But I did find a good warm & bright ivory that will pull that couch away from looking muddy and play well with the art for the walls.
Anyway, it's very funny to me, because *my* house looks like this -- as someone whose favorite colors are brown and taupe:
Decorating advice my mother *did* take from me today, though:
What you draw on paper won't match how the layout feels like when walking around in the actual room, so be prepared to move or even ditch furniture
You need area rugs to create little islands in an open plan space
Fixtures go a long way between a bathroom looking cheap / like a hotel room, and being cozy
You do not have to recreate your old room layouts when you move
You do not have to follow the "rules", such as a formal dining area
You can repurpose furniture to serve different needs - if you like the china hutch, but not the china anymore, put something else inside
A room should reflect how you plan to use it 90% of the time
Figure out what "entertaining" means to you - your parties do not have to look like someone else's, which influences how you change your space when company is over
An heirloom furniture piece that you already doubt will fit in a room will quickly become an albatross you come to resent, so consider parting with it now while you're still on good terms
