Hi all,

first post - so sorry if this is the wrong place - I saw the Adobe software forum but it didn't seem to fit...

I need to construct a visible spectrum gradient effect.

I have designed a diamond with a flare effect on the top right corner into which I have a 3 or 4 point white stroke at a diagonal. Where this diagonal emerges from the other side of the diamond I want to create a sort of perspective triangle filled with the visible light spectrum.

Sound fine so far, but when I use the pen tool and create the irregular triangle (actually it will be a polygon due to the intercepting of a border on the design but anyway...) I find that when filling it with the full colour spectrum gradient (and setting the appropiate angle) it is a symmetrical/flat fill (of course!) and what I need is the ability to squeeze the apex end down to a point and have the colours "fanning" out.

I tried this in various ways including rasterizing and so on but to no avail.

Can anyone help me with a technique that will assist me,.

Here are some very simple low res graphics to elucidate my question.

Not that I like them much, but have you looked at Mesh Gradients?
A Blend may work too. Just beware of stepping.

Well, you got us there in one piece.
But now we've hijacked the poor OP.
You still there Stardot?

yup. seems my original treatment didn't make it up...

here is what I have...

I have been working on some transparency effects to get the prismatic effect through the diamond but having no idea about gradient meshes I am about to start reading...

I know its kitch but I am trying to combine the subtelty of pure black and white gradients and single colour black with the brilliance of millions of colours with the prism effect. getting a kind of perspective or 3d effect is the next challenge but I got to get a pinch on the spectrum and then apply some kind of transparency (darken or multiply or some) to get it to filter throiugh the diamond from the glare point.

Thanks for a fast reply/s guys!

Is this what you're after? What program are you using? I did this in PS using Perspective and the applied a black>clear gradient.

Yes, just posting this while you replied!! I got similar result same way...

Best I could do by taking a rectangle spectrum blend from illustrator into photoshop and creating a perspective distortion, saving and placing back in ill and rotating and arranging to fit. Couldn't get a pleasing transparency so far but if anyone has any other suggestions on the design I would appreciate any.

As always just asking the question has made the process clearer to me...

I know its kitch - but anyway :)
