Match character color to lighting ?

Post by human »

Over at

viewtopic.php?t=10654

you folks patiently suffered through my struggles with the composition of a scene, including my usual tedious whining and weeping about color.

I wanted to update you with the following experiment. It might prove helpful when you need to harmonize character colors with the ambient color temperature.

( If the BIG picture doesn't show, Reload your browser )

This is an attempt to generate color keys for both the background and the character. As you recall from our last whiny episode, I had a breakthrough once I got enough sense to choose realistic colors for candlelight (whale-oil light, actually). (Let's face it, gold and black is a pretty elegant color scheme.)

Now, let's try to see what the character should look like in the room. The first thing to understand is that you need to be doing this kind of work in a paint program, not a vector program. So open the one you use.

It's hard to believe, in this setting, but there may actually be lighting conditions under which the original scheme A would work. (... I think ... !)

I started by copying A to a layer B. I add a translucent layer C which has been colorized at the room's color temperature -- orange. Then, with layers B and C overlapped, I keep adjusting the brightness and contrast of B and C until I feel the character belongs in the room.

As I said previously, I suspect that you have balance two opposing principles: the character needs to be higher contrast and more saturated than the background, but he also needs to be in harmony with the room.

The result is D, except that the hair was too brown, so I desaturated it. (The original color was F.)

The last experiment was to try to light the character by altering the inklines of the hair, as shown.

I hope this is helpful when you need to do this kind of thing, but I'm not sure I found the right colors yet. If you have any suggestions, I'm all ears.

Your image link doesn't seem to be working, but Adobe has an excellent free Flash based color scheme tool called Adobe Kuler:

Just click the "Create" option on the left to try it out. One of my favorite bookmarks for color design.

It's a fairly large image.

Refresh your browser, and hopefully that will load it.

I'm definitely in favor of color scheme generators, if they're good.

However, they are not a reliable way to color match an object to a background.

I can only assume the method I'm using here is probably similar to what color stylists do for cinema.

Refreshing your browser will not help. I got a 403, Access forbidden.

I saw the image.

Yes, you're on the right track with this. I wouldn't have done it with the tools you did, though. My tool of choice is the HSB colour slider since it's very much like mixing paint on a palette. (My father is a painter, so I grew up with this.)

Artificial light, like a candle, has always less different colour than daylight. That's why you start with a restricted palette. It is also less powerful (unless in a film studio), which means that you have less saturation in darker areas.

A face lit directly by a candle shows high contrast and its original colours, only dyed by the candle colour.

A face in shadow is only lit by reflected colour from some item in the room, so it has low contrast and is more or less monochromatic - one hue, only in different levels of brightness.

This is all basic painter's knowledge. You should be able to find it in a book about portrait or interiours painting.

Thanks tiger.

@Darth and Rasheed.

Whoops, my apologies. I've been increasing the security of my website and I may been overzealous about certain rules, such as, er... blocking all of the Netherlands... as I said, sorry.

Never mind, I just use a proxy server to view your images.

BTW If I were a hacker, I would do exactly the same, so it's no security at all, just an inconvenience for your less knowledgeable website visitors.
