A pretrained the color of a pair of pants classifier that sorts an image into one of 10 categories — what color the pair of pants is. Use the the color of a pair of pants 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 15 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 pair of pants 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.
Retailers can use the false image classification function to automatically categorize products based on the color of pants in customer-uploaded photos. This enables more efficient inventory management and enhances the shopping experience by allowing users to filter by color more effectively.
Online fashion platforms can leverage this function to suggest outfits based on the identified color of pants from user images. By analyzing colors, the system can recommend matching tops, accessories, and shoes, improving personalized user experiences.
Marketing firms can analyze the popularity of different colored pants in user-generated content on social media. This information can be used to inform advertising strategies and fashion trends while enhancing brand engagement by aligning with current styles.
Physical retailers can utilize insights from the classification function to optimize their store layouts based on the most popular pant colors identified through customer interactions or purchases. This data-driven approach can lead to increased sales and better inventory turnover.
Virtual stylists or apps can use this function to assess and provide personalized styling advice based on the user's existing wardrobe, specifically focusing on the color of pants. This can enhance client satisfaction by tailoring recommendations to their preferences and styles.
Fashion brands can analyze customer data regarding the colors of pants purchased or worn in images to create targeted marketing campaigns. This allows brands to tailor promotions and advertisements to better match customer interests and increase conversion rates.
Apparel companies can use the function to track the distribution of specific pant colors sold over time, aiding in sustainability reports and circular fashion initiatives. By understanding color trends, brands can make more informed decisions regarding production and waste management.
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 pair of pants 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.
