Not sure why the color shifts... but:
Create a color shift table (array of color shift values):
Create a property array for each element (triangle, square, circle): this
would contain, among other things (length of each side, original color,
current color, etc. etc. etc.)
If mouse click AND ctrl key is down (pressed), add element (triangle) to
group to be moved, if ctrl key is not down, remove all currently selected
elements from selected status and then add current element to selected
status
If mouse down AND mouse move begin drag/drop action.
Is that what you wanted?

While no stranger to PHP/MySQL and basic JavaScript, I could use some
major guidance on a project I wanted to try to put together. I'm not
sure how to go about it, but a little direction I think is all that I
need.
Basic Elements:
User can create any number of seven present rectangles (preset color
and size).
These rectangles can then be dragged, rotated 90 degrees, and/or
deleted.
The canvas or play area is divided into four quadrants. Each time
the rectangle is moved across the border between two quadrants, the
color is toggled (ex: a blue rectangle is dragged sideways and is now
in a new quedrant, and upon entering the quadrant, the color is
toggled to red. Upon dragging it to the next quadrant -- either to the
original or to another adjacent quadrant, the color is toggled back to
blue).
It would be best if multiple rectangles can be selected at once, and
it would be best if the mouse was the only input needed.
Any and all help is highly appreciated. This is destined to be a
functional algebra tiles manipulative to be used by my algebra
students. Thanks again for any direction!
