Rohit wants to create backgrounds having rainbow effect. Is it possible, if yes, how can he do it
Answers
Answer:
STEP ONE: Start a new document with a transparent background, sized 4235 x 2927. Select your color picker and choose your first color. Since we’re making a rainbow effect for this tutorial, we’re going to select a red tone #b62528. Using a large brush, simply paint your canvas to your liking. Try something a little different than ours! Don’t worry too much about perfection here.
STEP TWO: Next, head to FILTER > BLUR > GAUSSIAN BLUR. Choose a radius of 250 pixels. Press OK.
STEP THREE: Shift + Ctrl + N to create a new layer. Drag this layer beneath your first layer. Use your color picker and select for our next layer (orange). Paint with the orange, then repeat the blurring process found in step two. You’ll want to make sure that you paint some orange beneath the red so that they overlap a bit.
STEP FOUR: Repeat this entire process with yellow (#FFFF00), green (#008000), blue (#0000FF), indigo (#4b0082) and whichever colors that tickle your fancy, remembering to use a new layer for each color. (New layers should be added beneath older layers.)
To finish up, merge those layers together and name your file.
STEP FIVE: Next, File > Place your image into your document. Drag your image beneath your overlay.
STEP SIX: Now comes the fun part! Choose Layer > Layer Style > Blending Options (or the drop-down shortcut in your layers panel) and play with the options to get the effect you’re after. To get this effect, I chose the Color Burn blending mode. You can also stack the textures atop one another to really get a unique look. Have fun with it!
