Want to play with complementary colours? in rgb or srgb mode? Try this.
Nothing special, just messing around for a change, away from granites...

This gets complicated.
Are you just selecting complementary hues? Are you keeping saturation
and lightness the same?
What if you select complementary saturations and lightnesses as well?
What about Munsell system or CIELab? You are going to get different
values in those systems as well.

You are certainly right :-) However, I just wanted to keep it simple
while working on a scene, and get a colour complementary to another
there, without all the complications I know nothing about anyway. You
know, "I have this colour, what is its quick-and-dirty complement". That
kind of thing. As I said, nothing special, just handy to have at hand
while doing other things.

I admit that I did not followed the granite discussion (too much
entries). But red and blue are not complementary to each other in any
colour modell I knew. Blue is complementary to some shade of yellow and
red to some shade of green. There is a colour modell which takes red and
cyan and blue and orange as complementary, but I could not find red and
blue.

Also, keep in mind (and you already may have!) that the idea of
"complementary colors" was created for the RYB color model not RGB.

Basically, the idea is that colors diametrically opposed on the RYB
color wheel "go well" with each other, and colors diametrically opposed
on the RGB color wheel tend to "clash" heavily. I'm not sure why this is
the case, and why the RYB color wheel "looks nice" (at least in Western
art).

I have not seen a good explanation of this in my research.

Red, green and blue are the additive primaries, or RGB. Their usual
complement are the subtractive primaries : Magenta for green, yellow for
blue and cyan for red, or YCM.
This can obviously change if you use some other colour space.

An analog might be the major scale in music. The seven notes A to G are
not equidistant across an octave, yet they "sound nicer" (at least to
Westerners) so they are given greater weight/bias than the other five
tones. Dunno if it ultimately makes the life of someone learning music
for the first time easier or harder, though.

I am confusing "complementary colors" with "triadic colors".
Never mind, sorry.

Well... I do not want to open a can of worms here as I already did
apparently ;-)
So maybe... but as I already mentioned earlier, I am just messing around
to get something of a complementary (?) colour I can use and tweak as I
want afterwards in a scene. Consider it the equivalent of pressing paint
tubes on your palet and happily mixing the mess. :-) That is how I work,
really.
This whole exercise does not go beyond that. No hidden or arcane intentions.

Bad example, because the science behind musical harmony is reasonably
well understood. It all boils down to stuff the Pythagoreans already
knew about, which is all about the frequency ratios.
The only complication is the invention of temperaments, which introduce
a slight offset to just intonation to get some other benefits of musical
expression.

I would argue that the perceived "clash" of complementary colors in the
RGB system (highly saturated EGB colors, that is) is due to such colors
NEVER EVER occurring besides each other in the natural world. They
simply cannot. Because those extreme colours _per se_ can never be
achieved reflectively from natural white-ish light.
For example, to get pure RGB red, you need to blast out red light in
such a narrow spectral band, that the brightness within said band
exceeds the brightness within the corresponding band of natural
white-ish light.

Until you get into the really wild stuff of which 432 vs 440 is probably only
the tip of the iceberg. . .

I just think it's weird that colors 120 degrees apart from each other in
the RYB color wheel always "match", whereas nothing like that exists for
the RGB color wheel.

Though I suppose they could "match" only because we've always been
shown/told that they "match". I.e. tradition.

I like one of the comments:
"The 440 is tense/uptight. The 432 is richer, deeper and has clarity.
It’s more open, at least to me anyway."
I would agree 440 sounds a little tinny, less mellow.

When I was heavily into POV, I would see things in terms of shapes and
colors. Like, "That's a red pyramidal idea!" or "That's so blue cube!"
Now that I read and write more, I see things in terms of black print on
white paper; letters and sentences, and words rearranging themselves to
fit correct grammar. A musician might hear tones and see notes all the
time. A carpenter, linear forces (such as a hammer hitting a nail) and
simple geometry. Someone who watches movies a lot might think in terms
of two-dimensionally projected images. Likewise, people of the New Age
persuasion have their own language in which they view the world. (And,
no, language does not just exist in the mouth or written/printed word.)

My point is we are shaped by the things we spend most of our days doing,
or thinking about.
