The White Balance Selector in Adobe Lightroom Classic (also known as the Eyedropper tool) is an essential feature for correcting color casts caused by different light sources in your photos. To use this tool effectively, it’s important to select an area in your photo that is neutral in color, such as gray or white, without any color cast.
Here are some helpful tips for selecting the right area for white balance correction:
- Choose a neutral area: Look for a gray or white area in the photo that should not have any color cast. For example, a gray card, a white wall, or a white piece of clothing. You can also choose from some color numbers like 128, 128, 128 (RGB) for neutral gray, or 255, 255, 255 (RGB) for pure white.
- Avoid overexposed or underexposed areas: Make sure the selected area is not too bright or too dark, as it may not accurately represent the color temperature of the light source.
- Use a known reference point: If you have a color reference card, such as a ColorChecker, use the neutral gray patches on the card to set the correct white balance.
- Zoom in for better accuracy: Zoom in on the selected area to ensure you’re only selecting the pixels you want, and not accidentally including any surrounding colors.
Once you have selected an appropriate neutral area, click on it with the White Balance Selector, and Lightroom Classic will automatically adjust the white balance settings to neutralize any color casts in the image. If the result isn’t perfect, you can fine-tune the white balance manually using the Temperature and Tint sliders.

Common White Balance Mistakes
One frequent error is clicking on a colored surface instead of a neutral one. Selecting a slightly blue shirt or a warm wooden table tells Lightroom to compensate for that color, which shifts the entire image in the opposite direction. Always target surfaces that should be truly neutral. Another mistake is using the eyedropper on overexposed or underexposed areas. Clipped highlights and crushed shadows lack accurate color data, so the tool cannot calculate a reliable correction from those pixels.
When the Eyedropper Is Not Enough
Mixed lighting presents the biggest challenge for the White Balance Selector. A scene lit by both warm tungsten lamps and cool daylight from a window does not have a single correct white balance. In these situations, the eyedropper corrects for one light source but leaves the other looking off. The solution is to pick the dominant light source, correct for it, and then use local adjustment brushes to fine-tune areas lit by the secondary source. Lightroom’s Temperature and Tint sliders give you manual control to split the difference or lean toward the mood you prefer.
Using a Gray Card for Precision
For the most accurate results, photograph a gray card at the start of each lighting setup. Place the card where your subject will be and take a reference frame. In Lightroom, use the White Balance Selector on the gray card in that reference image, then copy the white balance settings to all the other photos from that setup. This method removes all guesswork and produces consistent, accurate color across an entire shoot.
