The Basic Color Editor can quickly adjust all the colors in an image, thereby correcting a color shift affecting the whole image. It is particularly useful, for example, when removing a color cast from artificial lighting. Use a Layer mask when correcting localized areas of an image.
Go to the Color tool tab.
Select the Basic tab in the Color Editor tool.
To select all the colors in the image, click on the multi-colored patch icon located on the very right of the color patch row. Ensure that the multi-color wheel is selected as it should have a frame around it.
Adjust the Hue slider while observing the effect on the screen. Moving the slider to the left shifts colors towards warmer colors (i.e., red) or to the right towards cooler colors (i.e., blue).
Adjust the Saturation slider.
Note that Lightness slider is disabled.
TIP: You can adjust the values on the sliders by scrolling the mouse wheel (make sure this feature is enabled in Capture One -> Preferences / Edit -> Preferences (macOS/Windows)). Alternatively, click inside the value field and use the Up/Down arrows on the keyboard to alter the number by a small increment, typically 1 or 0.1, depending on the parameter. Hold the Shift key and use the Up/Down arrows on the keyboard to alter the number by a larger increment.
Usage example: correcting a color shift across a sequence
When working with a timelapse shot using a strong ND filter, you may notice a consistent color cast (for example, magenta or green) across all images. To correct this efficiently, start by adjusting one reference image: go to the Color Tool tab, open the Color Editor (Basic), select the multi-color icon, and fine-tune the Hue and Saturation sliders until the color cast is neutralized. If needed, refine specific tones using the Advanced tab. Once the result looks accurate, save the adjustments as a Style and apply it to the rest of the images to ensure consistent color correction across the entire set.
