Colorimetric Workflow
How It Works
From chart capture to ISO-standard ΔE reports in five streamlined steps.
Phase 01
Prepare Scene
Choose a stable, even lighting setup, place the reference chart and sample on a flat surface, and avoid glare or shadows.
1
Phase 02
Detect Reference
Fill the frame with the color checker; the app auto-detects the 24 patches and shows a progress indicator during detection.
2
Phase 03
Build Calibration
Compute white‑balance gains and a color correction profile tailored to your device and lighting; store the profile locally.
3
Phase 04
Verify Accuracy
Review patch hits and ΔE summary; if any patches exceed tolerance, re‑frame or re‑capture to improve the fit.
4
Phase 05
Capture Sample
Lock exposure/focus, then capture a still or use the live stream to acquire a clean image of your sample.
5
Phase 06
Select ROI
Pick or refine the region of interest for analysis; handles orientation and mapping without uploading images to the cloud.
6
Phase 07
Compute Metrics
Calculate sRGB/linear/XYZ/Lab values, chromaticity (x,y), ΔE00 vs reference, dominant wavelength, and purity on‑device.
7
Phase 08
Save & Organize
Name your analysis, add tags/notes, and save locally for offline access and future comparisons.
8
Phase 09
Export & Share
Generate a PDF summary and share via the system share sheet; optional color‑name lookup enhances readability.
9
Phase 010
Recalibrate When Needed
If lighting or environment changes, run calibration again and manage multiple profiles to keep results consistent.

Laboratory Procedure
How to Calibrate & Measure ΔE
A reliable 5-step scientific protocol ensuring ΔE repeatability under any lighting condition.
- 01
Prepare Scene & Stabilize Lighting
Set uniform, diffuse lighting (D65 daylight or continuous 5000K). Avoid direct specular glare. Place the 24-patch Macbeth ColorChecker alongside the test specimen.
Uniform D65 Setup - 02
Auto-Detect Target & Compute CCM Profile
Frame the ColorChecker with your mobile camera. The CV engine auto-segments all 24 patches and computes a 3x3 Color Correction Matrix with channel white-balance gains.
24-Patch CV Fit - 03
Verify ISO/CIE ΔE₀₀ Tolerance Thresholds
Inspect the calculated per-patch CIEDE2000 ΔE₀₀ metrics. Colorium confirms if maximum error is within tolerance (ΔE < 1.0 golden pass).
ΔE₀₀ < 1.0 Pass - 04
Capture Specimen & Select Sub-Pixel ROI
Lock camera sensor exposure and focus. Tap or lasso the target region of interest (ROI) to apply statistical outlier rejection and Gaussian noise smoothing.
Lasso ROI Filtering - 05
Measure Exact Metrics & Export QA Certificate
Read real-time CIELAB (L*a*b*), CIE XYZ, sRGB, dominant wavelength, and chromaticity (x, y). Export certified PDF summaries or CSV swatch tables.

Knowledge Base & AEO Answers
Frequently Asked Questions
Clear, authoritative answers regarding colorimetry accuracy, device calibration, security, and supported standards.
Colorium Lab runs on modern iOS and Android smartphones and tablets. We target current OS releases on both platforms.
Core capture and color analysis work offline. Internet is needed for sign-in (Google/Apple), optional color name lookups, and diagnostics (analytics/crash/performance). There is no automatic cloud sync yet.
No, images are processed on-device and stored locally by default. If you export/share a PDF report, a temporary file is created for sharing. We never send your raw images to third-party services.
If you sign in: email/display name/provider info via Firebase Auth. For calibration/diagnostics: device model/OS/hardware info, and non-GPS EXIF fields (e.g., exposure, ISO) from selected images. We also collect anonymized analytics, crash, and performance data via Firebase. See the Privacy Policy for details.
Camera (capture for analysis), Photos/Media/Library (select/save images), Storage on Android (READ_MEDIA_IMAGES/READ_EXTERNAL_STORAGE for file access), and Network (sign-in, analytics, color name lookups). A microphone usage string exists on iOS, but current features do not record audio.
No. Colorium Lab is for research, education, and general informational use. It is not intended for diagnosis or clinical decision-making.
For best accuracy, use the built-in 5-step calibration with a Macbeth ColorChecker (or equivalent) under consistent lighting. Recalibrate when lighting changes.
Yes. You can generate and share a PDF calibration/analysis report using the system share sheet. Temporary files are created locally for sharing and can be removed.
Yes, guest mode works for capture and analysis with some gated features. Signing in with Google or Apple may unlock additional features now or in future updates.
Local data (samples, projects, calibration profiles) is stored on-device (Hive/shared preferences) within the OS sandbox and protected by device security. Network traffic (auth/analytics/lookups) uses TLS. We do not claim end‑to‑end encryption of your local content.
Firebase (Auth, Analytics, Crashlytics, Performance, App Check), Google Sign‑In, Sign in with Apple, and the color.pizza API for non-personal color name lookups.
Delete local samples/projects/calibration profiles from within the app or by uninstalling the app. For account deletion (Firebase Auth), use in‑app options or you can delete your data using the following legal link Delete Account.
