A pretrained the color of a curtain classifier that sorts an image into one of 10 categories — the color of a curtain. Use the the color of a curtain API immediately, no training required, then adapt it to your own data when you need more.
Drop in a photo and get the prediction back. No signup, no setup.
A sample of the 22 labels this pretrained classifier chooses between.

curl -X POST "https://www.nyckel.com/v1/functions/YOUR_FUNCTION_ID/invoke" \
-H "Authorization: Bearer $NYCKEL_ACCESS_TOKEN" \
-H "Content-Type: application/json" \
-d '{"data": "https://example.com/photo.jpg"}'Python

}Trained on a Nyckel-curated dataset covering 10 the color of a curtain categories, served on Nyckel's own infrastructure — your image stays on Nyckel.
Send an image URL or file to the invoke endpoint; the response is a label with a confidence score.
Clone it, then correct predictions and add your own samples in the console — Nyckel retrains automatically, turning this into a custom model tuned to your data.
This function can be used in home decor apps to help customers select curtains that match their existing interior design. By identifying the specific color of a curtain, the app can suggest complementary decor items, enhancing the user's shopping experience.
E-commerce platforms can leverage this image classification function to filter and categorize curtains based on their color. This allows customers to quickly find products that match their desired aesthetic, improving user satisfaction and boosting sales.
Virtual interior design services can use this technology to analyze images of a client's current curtains. This enables designers to recommend color-coordinated furniture and accessories, creating a cohesive look for the entire room.
Real estate platforms can employ this functionality to assess color schemes in staging images. By ensuring that curtains are complemented by the rest of the decor, real estate agents can enhance listings and attract potential buyers more effectively.
Businesses can utilize this function to analyze user-uploaded images of curtains on social media. By identifying popular colors, companies can optimize their ad targeting and inventory to align with current fashion trends and consumer preferences.
Property managers can implement this technology to classify and maintain a database of curtain colors in rental units. This assists in standardizing interior aesthetics across multiple properties, making it easier to manage and market the units.
Interior designers and bespoke curtain manufacturers can use this classification function to help clients visualize color options. By enabling instant color recognition, it simplifies the process of customizing curtains, ensuring clients receive precisely what they envision.
A zero-shot classifier uses a large foundation model's general knowledge to pick between your labels — no task-specific training, so new or edited labels work immediately. A Nyckel-trained classifier has been trained on labeled examples and runs on Nyckel's own infrastructure, which typically makes it faster, cheaper per call, and more accurate on data that resembles its training set. The "Under the hood" section on this page shows which kind this classifier is, and any classifier can be adapted into a trained one by adding your own examples.
Honestly: we can't know in advance — it depends on your data stream and how closely it resembles what this classifier has seen. The reliable way to find out is to measure it on your own data: start invoking the classifier with real traffic, or upload and annotate a set of images in the console — make sure they look like your production data, not idealized examples. Nyckel's evaluation metrics then show you exactly how it performs on that data before you rely on it.
No classifier is perfect, so Nyckel is built around the correction loop: invokes can be captured for review, you confirm or correct predictions in the console, and corrections become training data. Over time the model adapts to your data distribution — accuracy on your traffic improves with use rather than staying fixed.
No. This the color of a curtain classifier works out of the box — clone it into your console and you'll have your own API endpoint in under a minute. Training data only enters the picture when you want to adapt it: your corrected predictions and uploaded samples improve the model, and you can also edit the label set to match your needs.
Trying the classifier on this page is free with no signup. Cloning it requires a free account, and the free tier covers your first API calls each month — see nyckel.com/pricing for current limits and paid tiers.
Add this pretrained classifier to your Nyckel console — you'll get a live API endpoint in under a minute, and a path to a custom model when you need one.
