A comment came up inquiring to my thoughts as to
where the color's influence to the rendering of form
stood prominent acquiring the appearance of the
flesh tone in my working of Beau (?) thinking much
was accomplished by color more so than values.

You know...to my thinking, even the gray black
and white version here looks pretty good, which is
often a standard to judge if a painting holds well,
even so...not a lot of value variation is required in
the face to read believable.

In fact looking at such works as Sargent's "Lady
Agnew" or Mary Cassatt's painting of the bath...
converting the work to grayscale would show what
might seem little influence of value variation...
though color itself is playing a good part.

Perhaps such is a way to control unwanted blemishes
or things attributed to the appearance of aging...
something then that suggests well the fairness of a
lady's flesh or that of a child. In converting my own
work of Beau here to grayscale...you see how little
variation in values there really is letting you know
that color was more behind the rendering of form.

Here is Cassatt's work for comparison-
