I think someone is doing their school homework here (or using this forum as a personal training class).

I hate questions like that. There isn't enough information. There are 255 index colors. Using True color or Color Books you can have many more colors. But not unlimited. So I'd go for 255.

Hi,

 

>> I hate questions like that.

I fully aggree, I really really hate them,

Especially this question can't be answered (with one of those 4 given choices) as AutoCAD's entities can have 16mio colors (true color = 2^24 = 16777216) + "byLayer" + "byBlock", that are the values you can assign.

None of the choices are valid then.

Yes. But Civil Service test are just page after page of questions like that. What's ever worse is when the question is based on a sketch that looks like it was done in crayon by a 5 year old. Then you have to guess whether the inconsistencies in the sketch are part of the question of just bad drawing. I wont call it drafting because they never even use a straight edge.

 

Thanks for showing the math. I wasn't going to go that far.

Technically, if the question wasn't misstyped, it is horribly ungrammatical.

 

If the question is how many index colors there are, then it actually should be 257.

 

0 = byblock, 256 = bylayer, and 1-255.  

 

True colors have 256 * 256 * 256 possibilities. (2^24 possibilities)

 

I don't know how the XOR color of -1 (for grdraw lisp functions) might be factored in.
