[thelist] The use of color (was site header and logo)

[Alliax]

Simply to add that from the text on the page
http://www.liquisoft.com/color.html

I noticed also that instead of using a 180° rotation, using a +60° or -60°
for the rotation of the H angle, would provide the sort of effect this page
uses, colors that goes together well (blue and green)

Mastering the HSV model (and the small trigo maths involved, never worked it
out totally yet) would also provide more convenient ways of using the notion
of warm / cool colors than in RGB.

--
an example of using these notions would be:
if user's computer time is daylight, dynamic site shows a mix of warm colors
and some uses of complimentary colors.
if it's evening, night time uses cold colours, and all in nuances, by using
30 to 60° rotations only.

Good night.

Hello, thanks for both your and Ben's answers.

Thanks to Ben who's found the RGB2HSV function:
http://www.cs.rit.edu/~ncs/color/t_convert.html

Heather, I was not interrested in getting the inverse of a RGB color,
because I already worked the solution out, it wasn't that hard :-)
But as far as my art theory goes, inverse colours are not specialy useful
visually, except for black and white.. (perhaps I don't see the obvious
usefulness of inverse colours?)

It was just that I recently heard of a complimentary color to each color,
and I thought I could use that in order to create visually pleasing sites
without choosing the base colour myself.

Since I'll do it in PHP, I think once you have converted your RGB values to
HSV, you have to do a rotation of the H angle, change a little bit (random
offset) S and V values for not looking too rigid in the choice of colours.
Then you'll have to convert back your new HSV values to RGB in order to use
them in HTML table borders and likewise graphical elements on your page.

from what I understood, the rotation of H angle should be 180°
I take this from this page:
http://www.liquisoft.com/color.html
I think it's correct, I'll report to evolt about that after my tests if it's
wrong.

I'll do testing on toulonparadise.com as soon as I have the courage, surely
next year :-)

Thanks again
