A pretrained the color of a door classifier that sorts an image into one of 10 categories — the color of a door. Use the the color of a door 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 20 labels this pretrained classifier chooses between.
Need a label that isn't here? Clone the classifier into your Nyckel console and edit the label set to fit your data.
Once you've added this classifier to your console, you get your own copy of it behind your own endpoint. Invoke it with any HTTP client:
curl
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
import requests

}Trained on a Nyckel-curated dataset covering 10 the color of a door 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 use case involves integrating the color of door identification into smart home systems. Homeowners can customize their smart doorbells and security alerts based on the door color, enhancing the personalization of their home security features.
Online retailers can utilize door color identification to suggest complementary home decor items. By analyzing the door color from user-uploaded images, e-commerce platforms can recommend products that match or contrast tastefully with the existing home aesthetic.
Real estate agents can use door color insights in property listings to enhance visual appeal. By showcasing homes with trending or appealing door colors in marketing materials, agents can attract potential buyers and increase engagement.
City planners and urban designers can use door color classification data to analyze neighborhood aesthetics. Understanding community preferences for door color can guide recommendations for future developments and renovations that align with local tastes.
Home design applications can incorporate door color classification to aid users in visualizing home improvements. Users can upload photos of their homes and experiment with various door color options in a virtual setting to better comprehend design choices.
Insurance companies can analyze the colors of residential doors to assess property risk factors. Certain colors may be associated with specific neighborhood trends or stylistic choices that can inform underwriting practices and risk management strategies.
Local governments can implement community programs that encourage residents to paint their doors in approved colors for unity and aesthetics. Using door color identification, authorities can monitor participation in such programs and evaluate their impact on neighborhood cohesion.
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 door 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.
