Conical Rainbow Gradient?

[KidBrine]

The problem I'm having is that I need to know how to make a stupidly high resolution conical gradient with the colors #FF0000 # 00FF00 #0000FF

[Ego Eram Reputo]

In paint.net a conical gradient transitions between the Primary and Secondary colors. It looks a bit like this....

 

(Primary: black, Secondary:white. Repeat Reflected)

 

Where do you want the third color?

 

[KidBrine]

I'm essentially trying to get something like that but instead of having two colors (white at let's say 0 degrees and black at 180 degrees), I want three colors, Red at 0 degrees, Green at 120 degrees, and Blue at 240 Degrees.

I figured out something close after a sudden realization, will post steps later today.
still looking for perfect answer though 😕

Hi @KidBrine

 

You could do 3 different layers and work out the degrees:

 

 

P.S. I'm using an old version of paint.net as I've lost my new one for the moment 😫

This was done using pyrochild's Gradient Mapping Plugin.  If you want, I can post you a video on how to acheive it.  Quite easy.

That looks far from the ideal solution...

You could use Spoked Wheel to work out the angles quickly.  Render the wheel to your settings, Slightly modify with 3 central lines on a new layer ... delete the central axle > merge the lines to the circle > fill each section with your desired colour.  Draw your gradient on a new layer.  Play with Blend Modes

 

... and take more care than me when centering the conical gradient

I can't understand your directions, and the image provided has no gradient between colors

This is a great solution here!
It took a while to figure out the plugin (7 minutes) but after that it made perfect sense!

Your result looks like what you would get if you used the Effect>Render>Color Wheel on a square canvas and zoomed in with Layers>Rotate / zoom until the edge of the color wheel met the corner of the canvas space. Anyway I now understand what you where trying to achieve.

The render option "color wheel" doesn't seem to be built into paint.net

Thanks for providing the link, although the link is broken, it can be downloaded and installed if you add the .zip extension to the file after the download.

Do you want a bright or dark center?
