Problem:

To create a 3D cone with a rainbow spectrum that consist of 24 colors. Example of the final product should look like this:

enter image description here

Example #1 (what I have done so far):

  1. Create a circle and use the Line Segment Tool to divide it in half.

enter image description here

  1. Divide the circle into 24 parts (Effect -> Distort & Transform -> Transform)

  2. Set angle at 15 degrees and make 25 copies.

enter image description here

  1. I clicked Object -> Expand Appearance.

  2. I grouped all parts together and used Pathfinder -> Divide and then ungrouped all parts.

enter image description here

  1. I copied over some of the colors from the first picture using V and I to shift between select and Eyedropper Tool.

  2. The result became a rainbow circle and this is where I got stuck.

Desired outcome:

How do I proceed to take the circle rainbow and transform it into a 3D cone with gradient effect for the green and blue colors?

    You do not have any gradient yet. – Rafael Jan 26 at 19:07
  • @Rafael I was thinking of adding the gradient for the colors green and blue because these are the only ones visible in the cone. – kexxcream Jan 26 at 19:09

I can suggest a method to make the cone, but I think the gradients will probably have to be created manually. I can't really think of a quick way of doing them. Sorry about that.

Anyway, here goes:

  1. Select the circle and squish it into an oval

  2. Copy it, paste in front, and group the copy

  3. Hide the group

  4. Use the Lasso Tool to select the middle anchors

  5. Using the Direct Selection tool, click and drag the middle anchors down to make the cone

  6. Unhide the group you previously hid.

  7. From the centre outwards, select each section of the cone in turn, and do Object > Arrange > Send to Back. You can also use the keyboard shortcut for this: Shift+Ctrl/Command+[

  • Appreciate your time, this is what I was looking for. I do not mind doing manual work. – kexxcream Jan 26 at 20:20

    instead of sending to back why not just delete? Those shapes won't be used and just add clutter. – Luciano Jan 27 at 10:29
  • @Luciano - yes, you could since they are hidden anyway. – Billy Kerr Jan 27 at 15:53
