My thoughts on framing, some of them anyway
I define neutral framing as the items surrounding the art that enhance and help focus the art.
Some designers and framers say that neutral framing is a white or off-white mat and a specific style of frame.
My definition of neutral is to use the elements present in the artwork to design the frame presentation.
Design with consideration of the “relative’ period and style of the artwork. Is it an abstract, figurative or a landscape.
Does the style have an antique feel, or is it in the style of the ‘20s, 60‘s or ?....
All these elements may have an affect on the outcome of the design.
In other words the framing is "neutral" to the artwork.
Last, but not least, does it fit my personal style, can traditional be put with contemporary and visa versa or any other combination. Most of the time yes, but this may require comfort with a non-conforming look.
I generally suggest the most common color (the color of first impression) as the top mat, then use the second, third, or fourth colors, etc. for accents in order of strength. The stronger the color the less I suggest we use.
By framing this way the viewer's eye is not pulled from the art to the matting or framing.
If, when viewing art, your first impression is the frame or the mat, then the presentation is too strong for the image.
The viewer should want to linger on the art with visual excursions out to the framing presentation.
