This page describes the functions included in this edition of ColorThemePicker. Last reviewed: 6 November 2026. It must be rechecked if hosting, analytics or advertising services change.
Image color sampling
When you choose or paste an image, the Image Color Picker uses browser APIs to display and analyze its pixels. In the current version, these images are not sent to a ColorThemePicker application server for processing. Your picks and palette are used within your local browser session. You can clear an image using the tool's Clear control.
Color Studio preview photography
When you select a local photo for a Color Studio website, app or shop example, the browser checks and decodes that image locally before showing it. The file is kept in page memory as a temporary object URL for that preview; it is not uploaded to a ColorThemePicker processing server or saved in Studio’s localStorage draft. Replacing a photo, restoring the sample, or leaving the Studio releases the temporary image URL. Your five-color palette is saved separately.
Logo to Website previews
When you upload a logo to Logo to Website, its pixels are analyzed locally in your browser to suggest colors. To keep your logo visible while you navigate between the editor and its same-origin template preview, the current tool may temporarily store a scaled rasterized copy, optional brand name and website headline/description/button copy, inspector preferences and theme settings in your browser sessionStorage under ctp-brand-preview. Session storage is kept on your device and normally clears when the tab or browser session ends. No logo upload is sent to our application server. Clear your site data to remove the temporary session entry earlier.
Some optional interface demonstrations currently request images from third-party hosts, including Jiro's image CDN and Unsplash. Visiting a page that loads those examples may send standard connection data such as an IP address, user agent and referrer information to those hosts. Selected logo or CSS files are not included in those image requests. If a third-party image cannot load, some demonstrations use styled fallbacks while others may appear without photography. These dependencies must be checked for permissions and availability before production publication. Do not upload sensitive brand artwork to a public/shared device.
Palette preferences and local storage
Favorite palette identifiers can be saved in your browser's localStorage under ct-favorites-v1. The five-color Palette Studio automatically saves its current swatches, locks, harmony, preview mode and export preferences in localStorage under ctp-studio-session-v1 for recovery after reload. Choose Reset studio to replace that draft with defaults, or clear this site's browser storage. No images are stored by this draft feature. If you save Brand Intelligence theme versions, up to 12 sets of theme colors, selected template, optional brand name and website copy, and locked-role settings are kept in localStorage under ctp-brand-variants-v1. No uploaded logo image pixels are included in those saved versions or their JSON exports. The current logo preview remains separately in sessionStorage as described above. Theme editing, report generation, color calculation and CSS import operate locally in the browser. You can clear saved preferences through your browser's site-data controls.
Website CSS Migration Lab
When you import local CSS stylesheets or a ZIP archive into the CSS Migration Lab, file contents are read and analyzed inside your browser. Supported CSS entries are temporarily held in page memory so you can approve replacements and export a modified copy. The tool does not upload imported file contents to a ColorThemePicker application server, run code contained in those stylesheets, persist your files to localStorage, or contact the original websites referenced by CSS URLs. Exported ZIP files are generated and downloaded on your device. Imported files are cleared by the Clear analysis control or when the page is closed or reloaded. ZIP metadata and filenames are inspected locally with size, path and checksum limits.
Hosting and technical requests
Visiting this site makes standard network requests to the site's hosting provider, which may process connection information such as IP address, timestamps, user agent and request paths for security and delivery. The site also requests font resources from Google Fonts. Google's own privacy practices apply to those font requests.
Advertising and analytics
The version documented here does not load Google AdSense advertising scripts or an analytics tracker. Optional advertising layout previews appear only when explicitly requested using a preview parameter and do not load advertisements. If actual advertising, analytics or consent-management services are activated later, this notice needs to be updated before activation to describe the providers, cookies or similar technologies, purposes, controls and any required consent choices.
Website Doctor, offline use and local projects
Website Doctor reads HTML/CSS and ZIP entries that you select and prepares inert, sandboxed static previews locally; source code is not uploaded to an application service. The optional Save action stores the imported HTML, CSS, theme settings and decisions in your browser's IndexedDB, which persists until deleted or cleared by browser settings. The Image Contrast Lab analyzes uploaded photos in memory; images are not saved by that tool. A service worker caches same-origin website pages and assets for offline access after visiting the site. Clear the site's stored data to remove cached content and saved projects. On-device browser storage may be accessed by other people using your browser profile, so avoid storing confidential client materials on shared computers.
Design System Lab and browser-local reports
The Design System Lab compares locally imported CSS snapshots, computes matching color declarations, tests selected contrast constraints, generates approximate chart palettes and creates portable reports. Its optional Save action stores the brand name, imported CSS and HTML, theme colors, locks, previous CSS version and chart settings in the same IndexedDB project store used by Website Doctor. It does not send imported files to an application server. Exporting a complete project or report ZIP writes a copy of selected client source files to your device. Delete saved projects using their Delete buttons or clear this site’s browser data. Avoid confidential client code on shared computers.
Style Intelligence and SVG assets
Style Intelligence locally reads selected CSS, static HTML and ZIP files to generate source-level analysis of CSS overrides, custom properties, responsive rules and design values. Uploaded SVG assets are parsed and sanitized in your browser before preview or export; the generated logo variants, local code suggestions and printable HTML proposals are downloaded only when requested. The workspace does not send these selected files to a ColorThemePicker processing server or persist them in IndexedDB. Imported static previews use script-disabled sandboxed frames. Exported proposals may include a sanitized copy of your brand logo and locally calculated findings. Files remain in memory until you navigate away or reload the workspace. Browser-generated downloads are under your control.
Contrast audit worksheet
The optional multi-pair contrast worksheet runs entirely in your browser. Its edited role labels and HEX colors remain in page memory until you choose Save in browser, which writes a JSON worksheet into this site’s localStorage under ctp-contrast-audit-v1. The worksheet can be exported to a local CSV or JSON file, or restored from a JSON file you select; imports are parsed locally and are not sent to a ColorThemePicker processing server. Choose Remove saved copy within the worksheet or clear browser site data to delete the stored worksheet. People using the same browser profile may be able to view saved work.
Your choices
You can use the core tools without creating an account. You can reject an image upload, clear your current selections, delete stored theme versions using the delete buttons or browser site-data controls, and delete local palette favorites by clearing this site's storage, or configure your browser to restrict third-party resources. Restricting external fonts may change typography without disabling the color tools.
