Step 2: Now Select a rectangle and Fill with a colorful gradient inside the rectangle. so go to the gradient panel and select five different colors. i used Blue - Yellow - Green - red - Black .

Step 3: Now time to make an Ellipse. Go to the ellipse tool and make an ellipse on the rectangle.

Step 4: Fill the circular Black and white gradient inside the ellipse. See the below image. now apply the color dodge blending mode on it.

Step 5: We need to draw more ellipse around one which we have created earlier. apply same blending mode and color will be much brighter.
