Project Title: Web Developer Needed: Color-Matching Web App (Using CIELAB & Delta E 2000) Project Overview: I own a textile/thread business with a shade card of 700 unique colors. I need a lightweight, mobile-friendly web application where my staff can take a picture of a fabric sample, and the app will instantly tell them which of our 700 thread numbers is the closest match. Important Note on Accuracy (Please read carefully): I am looking for a developer who understands basic color science. You cannot use simple RGB Euclidean distance for this match. The math must convert the camera's RGB input into the CIELAB color space and use the Delta E 2000 (CIEDE2000) formula to find the closest match. I will be using a controlled lighting environment (an LED lightbox) to take the photos, so the camera input will be consistent. Your job is to ensure the math running against that input is 100% accurate. Core Features & User Flow: 1 Camera Access: A simple UI with a "Scan Cloth" button that opens the mobile device's native back camera. 2 Targeting UI: A square or crosshair overlay on the screen so the user knows exactly where to place the cloth in the frame. 3 Color Extraction: Once snapped, the app draws the photo to a hidden HTML5 Canvas, extracts the RGB pixels from the center target box, and averages them to get a single RGB value. 4 Color Matching: The app converts that extracted RGB value to CIELAB, calculates the Delta E 2000 distance against my database of 700 colors, and finds the closest match. (You can use open-source JS libraries like ⁠[login to view URL]⁠ or ⁠delta-e⁠ for this math). 5 Results Display: Show the top 3 closest matches, displaying the Thread ID Number, the Hex color preview, and the Delta E score for each. Data source - i have physical shade card i will sent it to you Tech- React/ node / mongodb

Hi, Your project is very interesting, and I completely understand the importance of accurate color science for textile/thread matching. I can help build a lightweight mobile-friendly web app using proper CIELAB conversion and Delta E 2000 calculations instead of inaccurate RGB distance methods. With experience in React, Node.js, image processing, and UI/UX, I can create a practical and reliable solution optimized for controlled lighting conditions like your LED lightbox setup. Once you send the physical shade card, I can help digitize and structure the color dataset properly for accurate comparisons. Looking forward to working with you. Best regards, Narendra

Hi, I can help with an instant, mobile-friendly color-matching web app that returns the closest thread numbers from your 700 shade card using CIELAB and Delta E 2000. I’ll build the React/Node/MongoDB app with a “Scan Cloth” flow, canvas-based center averaging, accurate RGB→CIELAB conversion, and Delta E 2000 matching against your stored Lab values. To reduce risk, we’ll validate the math end-to-end with your LED lightbox and a small calibration set before showing results (including top 3 with Delta E). Can you confirm your shade card’s target Lab values or whether we should compute them from physical samples you send? Also, do you want the crosshair box size adjustable by staff? I can start as soon as you share the format and sample setup.

I’m confident I’m the right fit for this role. Your project to develop a precise, mobile-friendly color-matching web app for your textile business perfectly aligns with my expertise. I will implement accurate color science by converting RGB inputs to CIELAB and using Delta E 2000 to ensure 100% reliable shade matching under your controlled lighting. The app will feature easy camera access, targeting UI, pixel extraction, and display top matches as requested, built with React, Node, and MongoDB. With extensive experience in UX/UI design, website redesign, modern interfaces, app and logo development, and AI integration, I bring a strong background in usability improvements and technical precision. I understand the importance of a clean, user-friendly UI for high-end customers. I’d love to chat about your project and offer a free consultation to discuss your exact needs and vision. Regards, Nabeel Ismail
