How to use Color Elements
Color Elements are saved HEX codes that let you lock in exact color matches across your image generations. Enter a value directly, and LTX Studio applies that color precisely to any image — from product color variations to full color grading and everything between.
Color Elements are available on Standard, Pro, and Enterprise plans. Enterprise users can also save colors to a Brand Kit for reuse across projects.
What are Color Elements?
Color Elements are saved HEX codes that lock in an exact color match across your generations. Enter your 6-digit HEX code, give it a name, and tag it into any prompt with @. LTX Studio applies that color precisely, whether to an entire image or specific objects within it.
How to create a Color Element
Saving a HEX code
- Open your project and go to the Elements workspace
- Click New Element and select the Color type
- Enter a name for your Element (something clear and reusable, like @BrandRed or @ProductBlue)
- Enter your HEX code, or select a color from the gradient panel
- Click Save Element
Color Elements require a standard six-character HEX code. Transparency values are not supported. If your color is in another format (like RGB or CMYK), convert it to HEX first.
Picking a color from an image
You can also pick a color directly from a generated or uploaded image in LTX Studio.
- In the Gen Space or Canvas prompt panel, set the generation mode to image
- Type
#in to the prompt bar. The color selector will open. - Type in a HEX, select a color from the gradient panel, or use the eyedropper tool to pick any visible color on the page. This includes any image within Gen Space or on your Canvas.
- Click Save as element at the bottom of the panel
- Name your Element and click Save Element to confirm
The color picker can be found when typing # into
the Gen
Space or Canvas
prompt bar. If the tool isn't appearing, ensure the generation mode is
set to image.
How to apply a Color Element in a generation
Color Elements can be tagged anywhere you generate images in LTX Studio, including Gen Space, Canvas, Storyboard, and Flows.
In the prompt bar:
- Type
@followed by your Element's name, or select it from the dropdown - Then describe what you want the color applied to. The more specific your prompt, the more accurate the result.
- Click Generate
Color Elements can't be tagged directly in video generation. Instead, apply your Color Element when generating the image, then use that image as a reference or start/end frame for your video generation.
Examples of Color Elements in action
Generate a product in a specific color
Use a Color Element alongside a product reference image (or saved Object Element) to generate a product in an exact color. Example prompt:
A clean studio shot of @ProductBottle in the color of @BrandBlue, white background, soft lighting.
Create color variations of an existing image
Useful if you have an image reference and want to swap the color of a specific element.
- Drag the image into the prompt bar to use as a reference
-
Tag a Color Element and describe the change –
Change the color to @ProductRed - Click Generate
- For more color variations, repeat the process, swapping @ProductRed for other colors
Tip: For more targeted control, use the Brush editing tool to paint over the specific area you want to recolor before generating.
Create a gradient with multiple colors
Tag multiple Color Elements in a single prompt to blend or layer colors. Useful for scenes with gradients or transitional tones.
A wide sunset sky over a calm ocean, transitioning from @SunsetOrange at the horizon to @DeepPurple overhead, golden hour light.
Color grade an image
Use a Color Element alongside a reference image to apply a specific tonal grade across an entire generation — useful for establishing a cinematic mood or matching a defined visual style.
- Drag or upload an image reference to the prompt bar
-
Tag a Color Element and describe the color change
Apply a hint of @MoodyTeal across the entire scene. - Click Generate
Tip: Try modifiers to adjust the level higher or lower, like "a hint of", "soft wash", "heavy color grade" or "drenched in".
Edit or delete Color Elements
- Within your project, go to the Elements workspace
- Hover over the Element
- Select the options menu (three dots) and click Edit or Delete
- (If you're editing your color, select your new one and click Save Element to confirm)
Once you click Save Element, there is no undo button. Instead of editing a HEX code, we recommend creating a new Color Element, then only deleting the original once you no longer need it.
Changing a Color Element's HEX code won't affect any generations you've already created. To apply the updated color, you'll need to regenerate those images. Check your color tag is pointing at the correct new Element before regenerating.
Color Elements and Brand Kit
Enterprise accounts can save Color Elements to a Brand Kit, making color palettes readily available for members to import into any project.
- Go to Brand Kits
- Select an existing Brand Kit, or create a new one
- Click New Element and follow the same steps as above
To create a Brand Kit, organization members must be assigned either an Account Owner or Creative Admin role. Account Owners can edit permissions under Roles. Standard Members cannot create or distribute Brand Kits, but can apply one to a project once an admin has set it up.
Frequently asked questions
Can I use RGB, CMYK, or Pantone values instead of HEX?
Not currently. Color Elements require a standard six-character HEX code. If your color is defined in another format, convert it to HEX first.
Can I apply more than one Color Element to a generation?
Yes, though the exact limit depends on the model. Most support between 8 and 14 Elements per prompt.
Why isn't my color matching exactly or applying to the wrong thing?
A few things affect color accuracy. First, be specific in your prompt about what the color should apply to — the more clearly you name the subject, the more precisely the model targets it. If you need to isolate a specific area, use the Brush tool for added control.
Lighting also plays a role. The model renders color intelligently in context, so the lighting conditions in your image or prompt can shift how a color appears. Adjusting your prompt's lighting description can help.
Also check that your HEX code is correct — a small typo can shift the color significantly. If you're still seeing issues, try switching models. Nano Banana models and GPT Image 2 tend to handle exact color matching and realistic color grading most consistently.
Where can I use Color Elements in LTX Studio?
Color Elements work across all image generation tools in LTX Studio — Gen Space, Canvas, Storyboard, and Flows — and can be combined with other Elements and reference images.
Can I use Color Elements in video generations?
Not directly. For video, apply your Color Element at the image generation stage first. Once you have a generated image, convert it to motion by using it as a reference image for image-to-video generation.
Which model works best with Color Elements?
All models should handle Color Elements well, but some models are better optimized and results vary by model. Here's a general guide based on how each handles color:
Nano Banana — best overall for exact HEX color matching and realistic color grading. A good default if color accuracy is a priority.
GPT Image — strong color accuracy and a close alternative to Nano Banana. Handles both targeted colors and grading well.
Flux.2 — can produce good results for color grading, especially with a softened prompt (e.g., asking it to maintain some of the original coloring). Less reliable for targeting specific objects or matching exact HEX values.
Z-Image — mixed results. Can handle some targeted product colors, but struggles with color grading tasks.
Can I use HEX codes without a Color Element?
Yes. In the Gen Space or Canvas prompt bar, type #
to open
the
color selector and enter a HEX code directly. This applies
the
color to that generation without saving it as an Element.
You'll
need to enter the HEX code manually each time, as it won't
be
saved for reuse.
