Rainbows can be observed whenever there are water drops in the air and sunlight shining from behind a person at a low altitude angle (on the ground). The most spectacular rainbow displays happen when half of the sky is still dark with draining clouds and the observer is at a spot with clear sky in the direction of the Sun. The result is a luminous rainbow that contrasts with the darkened background. ...from Wikipedia.
And now... this trick teaches you how to create a rainbow in a few steps using gradient presets in Photoshop CS.
Open an image on which you wish to add the rainbow. Press D. (to set default foreground and background colors, kinda magic isn't it?) Create a new layer by clicking on the 'Create a new layer' icon at the bottom of the layers panel.
With the new layer selected, click on the Gradient tool
on the tool bar. Now the gradient properties will be displayed just below the main menu as in the image below. Give similar settings as in this image. Next click on the gradient image (marked in red below)
The Gradient Editor will be displayed as in the image on the right.
From the presets, select the sixth colored box on the second row. Below you'll see the colored bar with pencil icons called tab stops.
Drag on these color tabs and reduce the width and opacity using the opacity tabs above. Experiment the different tab stops and you will have an idea what each tab stop is meant for. If you wish to remove any tab stop just drag the tab stop out of the window.
Add a new tab stop with the color orange. To create a new tab stop just click on the bottom border of the rectangle, a new color tab stop with the same color to its next color stop. By clicking on this color tab stop you can change the color. Drag the colors to the right side.
This is how the settings look after all the changes.
After you create the new gradient, click on OK. Now you'll see this gradient in the gradient properties bar (below the main menu).
From the gradient properties select the radial gradient, place the cursor at the bottom left corner and drag it to the top middle edge of the image. (Try out different positions till the rainbow position suits your image)
On the layers panel change the opacity to 21%. In the final image if you wish to erase any part of the rainbow that appears out of place you can use the eraser tool with a brush size between 24 to 36 and erase the unwanted portion.
Here we go! The picture with a colorful rainbow!
