A complementary color split is a fun and striking photography technique that allows you to split an image into two complementary colors. Complementary colors are colors that are directly opposite each other on the color wheel, such as red and green or blue and orange. When complementary colors are placed next to each other, they create maximum contrast and make each other appear more vibrant. This technique can add visual interest and an artistic flair to your photos.
A complementary color split is achieved in post-processing by using photo editing software to isolate specific color channels and split the image into two separate photos featuring complementary colors. The most common splits are red/cyan, green/magenta, and blue/yellow. With some creativity and practice, you can use this effect to produce eye-catching abstract art images as well as add a unique spin to portraits, landscapes, and more.
Here’s a step-by-step guide to help you understand the basics of creating a complementary color split effect with your photos:
Choosing an Image
The first step is choosing an appropriate image to apply a complementary color split to. Images with bright, prominent colors tend to work best. Some examples include:
– Portraits with colorful clothing or backgrounds
– Nature scenes with vibrant flowers or foliage
– Urban landscapes with graffiti art or neon signs
– Still life photos of fruit arrangements or decorated cakes
Simple compositions also tend to be most effective for color splits. Busy or cluttered images with too many elements and colors competing can end up looking too chaotic when split.
Think about which two complementary colors you want to feature and look for a photo that has those shades prominently featured. For example, a portrait with a bright blue background would be ideal for a yellow/blue split.
You can also shoot a photo specifically for this technique. Use colored gels, props, backgrounds, or clothing to selectively incorporate the colors you want into the image.
Editing Software
To create a complementary color split, you’ll need photo editing software that allows you to adjust individual color channels. Here are some options:
– Adobe Photoshop: The industry standard for photo manipulation. Provides full control over color channels.
– GIMP: Free open-source image editing software with color channel control.
– Affinity Photo: Photoshop alternative with advanced masking capabilities.
– Pixelmator: User-friendly image editor for Mac with color adjustment tools.
– Photopea: Free browser-based editing program with channel mixing options.
Make sure your chosen software includes the ability to view and export color channels individually. This is required to isolate and split the complementary colors.
Isolating Color Channels
Now it’s time to open your selected image in your editing software and isolate the two complementary color channels:
1. First, make any desired basic edits to your photo, such as cropping, exposure adjustments, or sharpening.
2. Go to the Channels panel (in Photoshop) or Channels view. This displays the color channels – Red, Green, and Blue.
3. To isolate an individual channel, click on it in the Channels panel to view just that color.
4. With the channel selected, copy it (Ctrl/Command-C) and paste it into a new layer (Ctrl/Command-V).
5. Repeat this for the other complementary color channel.
For example, to create a red/cyan split, you would copy and paste the red and cyan (blue) channels into separate layers.
This will give you two color layers that you can now work with separately.
Masking
Once you have the individual color layers, it’s time to mask them into different sections of the image:
1. Add a layer mask to the top layer. The layer mask allows you to selectively hide parts of a layer without destroying the pixels.
2. Paint with black on the layer mask to hide areas and white to reveal areas. Black conceals and white reveals.
3. Use a soft brush with varying opacity to blend the transition between the two colors.
4. Experiment with different patterns, shapes, and angles in your masking. You can mimic the original shapes in the photo or create graphical geometric patterns.
5. Use the eyeball icon on the layers panel to turn visibility on and off as you work to preview the split effect.
Take your time with this step to finesse the split line between the colors. The masking controls which areas appear in each complementary color.
Color Adjustments
Once you’ve split and masked the image into complementary colors, you may wish to adjust the hue, saturation, or brightness of each layer:
– Boost the Saturation to make the colors vivid and intense.
– Adjust Hue to shift the colors closer to their direct complements on the color wheel.
– Lower the Brightness on one layer so the colors are asymmetric in value.
– Use Levels or Curves adjustments to target specific tonal ranges.
Don’t overdo it on the adjustments or you’ll start losing the natural color splitting effect. Subtle enhancements are best for maintaining realism.
You can also apply photo filters like Gradient Map and Selective Color to transform the color cast.
Finishing Touches
The last steps are finishing touches to complete the split effect:
– Crop your image to finalise the composition. A square or portrait crop often works well.
– Optionally, convert the image to black and white. This creates a more graphic, stylized look.
– Consider adding a simple black border or white stroke to define the edges.
– Flatten down your layers into one composite image.
– Sharpen the final image to increase clarity and detail.
When you’re satisfied with the result, save and export the finished color split photo. JPEG is ideal for photos and PNG for transparent backgrounds.
Image Examples
Here are a few examples of complementary color splits created using the techniques outlined above:
| Original Photo | Red/Cyan Split |
 |
 |
| Original Photo | Magenta/Green Split |
 |
 |
| Original Photo | Yellow/Blue Split |
 |

As you can see, the complementary color split effect provides an interesting way to transform a photo into a graphic, two-tone image.
Creative Variations
Once you understand the basics, feel free to get creative and experiment with different variations on the complementary color split:
– Use a non-standard color pair like red/blue or purple/yellow.
– Split into three or more colors for a tri-color effect.
– Try an HSL split instead of RGB for different color combinations.
– Offset the split line or curve it into interesting shapes and patterns.
– Split toning: Tint the shadows one color and highlights another.
– Use textured brushes and overlays to make artistic custom split edges.
– Include subtle amounts of third colors for unique color palette.
– Split based on light source, not color, for a halves/thirds lighting effect.
– Stack color splits with different split line angles for a kaleidoscope effect.
– Apply only selectively to certain subjects or areas of a photo.
– Incorporate grain, textures, glitter, or other elements into one of the color layers.
The possibilities are endless so explore and find a unique complementary color split style of your own.
Pro Tips
Use these pro tips to take your color split photos to the next level:
– When photographing for a split, expose normally and focus on composition. Avoid blown or lost detail.
– Use channels instead of colored filters for accurate complementary colors.
– Keep adjustments subtle. Overdoing contrast, saturation, etc. looks unnatural.
– Mask and blend with low opacity brushes to create soft, feathered edges.
– Try Frequency Separation filtering for perfectly smooth color gradients.
– Use curves, levels, or dodging/burning to equalize the layer tones.
– Add a curves layer mask to selectively adjust each color’s brightness.
– Pay attention to how the tones of the original image translate into the split versions.
– Save your work in progress regularly so you can always go back if needed.
– Crop symmetrically for a balanced mirrored split effect.
– Watch for halos, fringing, and artifacts along high contrast edges.
Conclusion
Complementary color splitting is an innovative technique that adds a strikinggraphic element to ordinary photos. By isolating key color channels and using masking techniques, you can create brilliant two-tone images. With practice, you’ll be able to produce polished, professional effects. Let your creativity run wild and have fun seeing your photos in a bold new color separated light. The world is full of amazing images just waiting to be split into vibrant complementary colors.
