This is my attempt to look further into the point made by blockwave. Let's look at how the following raw text will be formatted.
Text
The quick red fox jumped over the lazy dog. The quick red fox jumped over the lazy dog. The quick red fox jumped over the lazy dog.
>The quick red fox jumped over the lazy dog. The quick red fox jumped over the lazy dog. The quick red fox jumped over the lazy dog.
Inline code
`Plot[Sin[x], {x, 0, π}]`
>`Plot[Sin[x], {x, 0, π}]`
Block code
Plot[Sin[x], {x, 0, π}]
Plot[Sin[x], {x, 0, π}]
> Plot[Sin[x],{x, 0, π}]
Plot[Sin[x], {x, 0, π}]
The result of formatting is:
Text
The quick red fox jumped over the lazy dog. The quick red fox jumped over the lazy dog. The quick red fox jumped over the lazy dog.
The quick red fox jumped over the lazy dog. The quick red fox jumped over the lazy dog. The quick red fox jumped over the lazy dog.
Inline code
Plot[Sin[x], {x, 0, π}]
Plot[Sin[x], {x, 0, π}]
Block code
Plot[Sin[x], {x, 0, π}]
Plot[Sin[x], {x, 0, π}]
Plot[Sin[x],{x, 0, π}]
Plot[Sin[x], {x, 0, π}]
I would say that the background gray used for the quotation environment is exactly the same gray as used for both the inline and block code environments. Further, the utility I use to read the RGB values of pixels on my screen agrees with my assessment.

. Furthermore I tested using different left border colors (one color, two colors), but didn't like that. Of course it doesn't make a dedicated output style unnecessary, but adds an easy way to test different possibilities by modifying that style file. We really should have an ouput-citing style in addition to a text-citing style. – Karsten 7. Aug 29 '16 at 8:00
