How to Use Secondary Color Correction in Avid

The secondary color correction avid allows the user to select a portion of an image and to correct the range of colors in that selection without changing anything else in the image. This feature will help you edit skin tone, certain objects in the image, or even the background.

Step 1: Open the Color Wheels

Once you are in the color correction mode, you need to click on the Sec tab. You should see two color wheels come up. Each wheel has a vector or wedge that represents a preset range of colors. The spots are coded by R for red, B for blue, and YL for yellow, for example.

The wheel on the left is called the input wheel. This wheel determines the selection of definition colors that need to be changed. The wheel on the right is called the Output wheel and it is also coded with R for red, B for blue, etc. 

Step 2: Change the Colors

To change the color, pick the selection you want to change the color range for on the wheel on the left. To do this, just move the color vector to a different spot on the wheel and then drag that wedge over to the other wheel. This is the basic procedure for a secondary color correction. All of the other features in this section are just used to fine tune this process.

Avid gives you twelve predetermined color vectors set up in your features tab. Of these twelve preset colors, only six display, again by default. If you need to use a color not on the input wheel, then you can use the Color Selection Buttons.

Step 3: Fine Tuning

Locate the syringe tool on the panel and click on it. Drag it over the section of the image you want to change and without letting off the left mouse button. Once you let go, then the preset vector closest to the color to be changed on the image is adjusted to match the color tones on the selection (and then isolates that section).

Once the color is changed, you can use the eyedroppers on the panel to fine tune the colors and to do touch-ups.

Step 4: Changing Custom Colors

The color vector can also be changed by using the sliding scales on the left for the input and right for the output. Here we have the hue slider and saturation slider which change the color but not the shape. Saturation and hue width change the shape of the vector.

When you need to change the output wheel, simply drag the color vector from the input wheel to the output wheel. If you invert the color vector, then all the colors in the image will be changed. You can also edit the colors in the output wheel. The slide scale changes tone and luminance.

You can also turn on or off the color vectors so you can check out the final outcome before you save. Keep in mind if you work with more than one color vector, the second one can change or affect the color of the first one.
