This is because edge detection tries to find out significant transitions in luminosity/brightness in an image. Therefore grayscale images are used, since in grayscale the brightness of an image is modeled.
You can of course use other characteristics of a pixel (like the red color) if the scene is illuminated in red or if the edges to be detected belong to objects that reflect the red color specter most.

What is use of filter in image processing?
Very many actions taken while processing images can be referred to as filtering. There are distortions and blurring and edge detection and color enhancements and all sorts of effects that fall under the "filtering" domain.
What do you need to know before you can write shape recognition programs for c plus plus?
Shape detection requires a slew of techniques, including edge detection, pattern matching, probability analysis, feature detection, middle mass and blob detection, image correlation and pixel classification. Recognising simple shapes like triangles, squares and circles is relatively easy. Use edge detection to find the border line and count the number of edges. If one line, it's a circle, three is a triangle and four is a square. You can then analyse the lengths and angles to determine more specific information, such as ellipse, right-angled triangle, rhomboid, parallelogram and so on. For more complex shapes, you'll need to use pattern matching, feature detection and probability analysis. The remaining techniques are primarily used for detecting 3D planes in a 2D image, separation and classification of objects and so on.

What are the usage tracing paper?
tracing paper is a thin paper (usually light gray) that you lay over an image - the image underneath can be seen well enough to be traced over with a pen or pencil. artists use tracing paper to copy an image or just to verify overall proportions before they commit it to permanent paper
