what "chromatic situations" are

okay I know what "chromatic situations" are but what would you call situations with just lines and not colors...

Also...a line can go in a direction from 1-360 degrees right?

Thanks

A line can go in any direction, it's not limited to just one plane. I don't know what else you're trying to ask about lines, but I doubt it belongs in this forum.

I mean, a line can only curve between 1 and 360 degrees right?

Lines don't curve, by definition.

Black lines on white paper would be called "monochromatic."

Degrees are for measuring angles, not lines. Line are usually just described as horizontal, vertical, or diagonal. If you want to get more specific in describing the direction of a line you'd have to tell us where you want to put it. Is it just on paper? Or does it exist in space somewhere? Lines on the earth's surface can be described relative to some point on the compass: north-south, east-west, etc.

Monochromatic means that there is just one wavelength, the white light consists of many wavelenghts and so is not monochromatic. From pure black no light is coming.

(I am not sure what Needbioinfo is asking, but any visual scene is a "chromatic situation", also a scene with only lines...)

Yes, the white paper is not monochromatic. For some reason there doesn't seem to be a proper term in use for black ink, and printers refer to something printed all in black the same as they would something all in red, or all in blue. Black is misrefered to as a color in this situation, but that is how things hve come to be.

Also, people who are completely color blind are called monochromats instead of something like achromats. I don't know why.
