Various Methods used by Photographers to Obtain Vibrant Colors in Photographs
Use of Filters
Circular Polarizer: A simple method of making colors vibrant in a photograph is to use a circular polarizer while shooting. This helps reduce glare, and increase color saturation thereby bringing out the rich colors in a scene.
Graduated Neutral Density Filter: Proper exposure is very important to obtain good colors in landscape images. Many landscapes have uneven lighting over large areas and such photographs tend to end up with the sky looking dull and flat or overexposed. A graduated neutral density filter can be used to avoid this and bring out the rich colors in the sky.
Bracketing and HDR Photography
Sometimes, the difference between a photograph with dull colors and another with vibrant colors is whether the exposure is correct or not. When in doubt, the best course of action is to bracket the photos. This also gives us the option of combining these bracketed shots into HDR photos. HDR stands for High Dynamic Range and is especially suitable to bring out the various colors in landscape, sunsets, etc.

Using Reflected Images
Another technique to bring out vibrant colors in a photograph is to use reflections off water bodies, glass buildings, etc. to fill the frame with rich colors. However, this technique cannot be used in the absence of a suitable reflecting medium.
Importance of Contrast in Photography
Another method to do this is to understand the importance of contrast in photography and how it plays an important role in composing an image.
