Working with Photoshop Color Range
Photoshop guys are very familiar with the color range option of Adobe Photoshop. Color range command is a great tool for selecting the areas of an image based on sampled color. And its somewhat similar to Magic Wand Tool. In Magic Wand Tool you need to manually click on the areas of an image that needs to be selected. But if you use the color range option, you just need to choose the sample color. And Photoshop will make the selection by itself!
This tutorial applies to all running versions of Adobe Photoshop including CS4, CS5 and CS6. But Ive prepared the tutorial using Photoshop CS5. All the images of this post will be based on Photoshop CS5.
Color Range
Color Range belongs to the Selection part of Photoshop. You will find it under the Select Menu. Run Photoshop from your PC > Open an image from your hard disk > Go to the Select menu > Choose Color Range. You will get the following image:
Have you noticed Marks PC Logo on color range window? Here the white part is currently selected. If you would like to expand the selection area then click on the pencil button from the right side with plus mark. Now go to your image and hit on the part that you want to add to your selection.
Make sure Sapmled Colors is enabled in the Select option.
You can also increase/ decrease the amount of Fuziness adjust the selection. If you make any wrong selection or if youd like to remove something from your selection then choose the Pencil button with negative sign. Then hit on the part of image you want to deslect.
Eyedropper Tools
The three tools just below the Save button is know as eyedropper tools. The left one is called Eydropper, middle one is Add to Sample and the right one is Substract from Sample.
Fuziness and Range
Ive told earlier that Fuziness will control the amount of selection. By increasing and decreasing the range, you can control the amount of selection. And Range will control how much area of the image will be selected.
To be honest, color range command is somewhat difficult to explain. You need to practice it by yourselft. If you click on the options, increase or decrease the value of different fields, you can easily understand. So, try to explore!

Change Photoshop Transparency Grid Color!!
If youre a Photoshop user, you must know about transparency grid. Transparency Grid is a checkerboard which appears when youre working with an image with transparent background. If your image has no color in the background, this checkerboard appears behind the image.
Okay fine. Transparency will be indicated by the checkerboard. But you may ask, why I will change the color of transparency grid. In this post Im gonna answer this question. And I will also show, how to change the color of the transparency grid.
Why to Change?
Suppose youve an image with white background. And you need to remove this background behind the image. You know there are different ways to remove background. Im not gonna discuss it here.
In the critical part of the image, Magic selection tool may not be able to select the white part. In that situation you can manually select the unselected portion. But you may also fail remove the white background properly. Because you cant select the white background as your default transparency grid is looks like a checkerboard that contains white color! So after saving the image you will notice there are some scattered white spots in the background.
To get rid of this problem, you can change the default transparent grid.
How to Change?
Very simple. Im using Photoshop CS5. Run Adobe Photoshop from your PC and follow the instruction -
- Go to the Edit Menu.
- Select Preferences > Choose Transparency & Gamut.
- Now you will get the Preferences window with Transparency option selected.
- Keep the Grid size Medium or as your wish.
- Choose Dark from Grid Colors. Or you can customize the color using the custom option. You can also use any other color from the list if any of them is suitable for you.
- Hit OK after choosing the Grid colors.
Remember, the default grid color may need to changed when youre gonna remove any white background from your image. Or background that is light black. Otherwise you dont need to change it.
Turning off the Grid!
You can totally turn off the grid! Yes! If youre bored with the grid that is shown for transparent layer, then you can turn off the grid from preferences window.
Go to the Grid size as shown in the image above. And choose None. Now create a new document from your Photoshop with transparent layer. You will just see white background instead of a grid. But your image will have transparent layer.
