Is Albers' Method Alone the Best Way to Study Color?

In Albers' color studies there is no mixing.

Albers found mixing too messy and the results
of brushwork too unreliable.

Yet, the Albers color studies are exciting because
of what happens when one piece of colored paper is
placed next to another.

You have to wonder though, is Albers' method the
only way to study color?

Isn't it just as valuable to study what happens when
a specific cobalt blue meets up with a delicious
hansa yellow?

Or a particular pyrolle red merges freely with a
primary cyan?

What happens when colors mix?

Aren't those sorts of delights a compelling PhD
level study all on their own?
