I desperately need some help choosing an exterior paint for my house in Boston. I want a gray/charcoal that has an undertone of blue (versus brown or black or yellow) and I want a few choices so I can order swatches from Samplize to see what it looks like before I really swatch. I need a trim color as well and I want a fun door color (in the greens or blue family). My house is a farm cottage style but I want to go as modern with colors as I can (see photos below). Any advice would be appreciated.
