Understanding color-temperature relationships

[Gigalot]

Until you try to paint green leaves in a gray vase, Dave. There are no color temperature relationship! Only hue green and hue gray

It will be a very fun painting Sid!

If you stick some green leaves in a gray vase and stand it in the light, depending on the light source you will observe colour temperature harmonies between the light and the shadows. So the colour temperature relationships are in the subject before you start painting, don’t make life unnecessarily complex, chose the easy path of understanding and seeing temperature relationships.

Than, Dave, you need at least 2 light source. One diffused light for shadows with high color temperature (sky light) and the second (direct sun light) with lower color temperature. That is an ordinary situation for landscape painting.

I understand now what people wanted to say to me (us) using "color temperature relationship" term. You mean something like 3D modeling "ray tracing scene rendering" term, a complex of whole scene lights and reflections which gives realistic form to all available objects.

You seem to be determined to make life difficult for yourself Alex , you will be suggesting next that I take into consideration Wave Particle Duality. Dave

at this point i must quote gary coleman and say "whatchu talkin bout willis?"

[Gigalot]

Wave Particle Duality? If our eyes can see it, we can use it in painting. Another question is "why?", "were?" and "how?"

Remember: science has always been a tool for painting!

I just talking about HUE VALUE CHROMA. And you know more?

I can definitely agree with this. Many very effective paintings are painted with the "wrong" colours if the objective is to match the natural local colour. But the end result looks "right" because the relations between the colours are right.

The answer to the question "which is warmer a red-orange or a yellow-orange?" depends in part on whether red or yellow is "warmer". If red is defined as being warmer, then the more a colour leans towards red the warmer it must be. If I define green as " warm" the colours will be more or less "warm" relative to whether they lean towards or away from green.

It is a relative quality. There is some Platonic ideal "warm" colour, all colours are warm to the degree that they share in the qualities of this ideal "warm". All colours are cool to the degree in which they differ from the qualities of the ideal "warm". "Warmness" it self is an abstract construct. I do not believ you can show me the colour "warm". Hue, Value, Chroma. These do not include temperature.

I suppose a "scientific" arrangement of colour "temperature" could be made based on wavelength in the spectrum. The closer to infrared the warmer a colour, the closer to ultraviolet the cooler a colour. However I don't think temperature is customarily measured or described by wavelength of the electro-magnetic spectrum, at least not by most people.

ok, if you aren't talking temperature then that explains it, but here is the thread title again: "Understanding color-temperature relationships"

And then ,unfortunately, other people can`t understand what it really meant.

I guess, you are right.
Everyone will understand it in their own understanding Also if your understanding is better than others understanding, you can reach a better result, which is more important than understanding.

[Horsa]

Yes, I think it is the results that matter in the end.

I have no problem with assuming that colour temperature is a valid concept and an appropriate model for colour behavior when I click on a thread titled "understanding colour temperature relationships". I sort of expect the discussion to be about colour temperature.

Excuse if this link has already been posted. Includes some history.

Since the term was coined in the 18th century, this means that most of the great artists of the past worked fine without "color temperature" concept.
Also, Preraphaelites (I love their color harmony!) criticized this term.

I do not mind the term. It simply limits me to choosing my colors. Do not look at me! Use this term if you love and find it is useful.

The term may have become more fashionable centuries ago but the concept has existed in humans for their entire existence here on earth. Lioncloth designers and interior decorators back in the caves were thinking it
Temperature doesn't limit any color choice. From a vast amount of experience in thinking in terms of color temperature I can verify this.
quote from einion:

The only thing in vision is colour, which encompasses all three dimensions. There isn't a fourth

Therefore color temperature is a term that is similar in nature to the one you used above, ie. color harmony. There is no color harmony in hue, value, and chroma. there is no other dimension of color than those three, ergo any "color harmony" must be differences in hue, value, and chroma only.

btw, is there a better way to think of color harmony? if so , explain pls, thnx!
