ArtistAssistApp, also known as Artist Assist App, is a web app for artists to accurately mix any color from a photo, analyze tonal values, turn a photo into an outline, draw with the grid method, paint with a limited palette, simplify a photo, remove the background from an image, compare photos pairwise, and more.
Hello, artists! I am pleased to announce the latest update to the ArtistAssistApp, released in November 2025. This time, there are some major new features in addition to the usual stability and performance improvements.
Let's take a look at what's new since the last major update in August 2025!
- Adjusting White Balance Using the Percentile and Reference Methods
- Add Margins for the Tape When Printing the Outline on Multiple Pages
- Color Temperature Estimation: Warm and Cool Colors
- Automatic Backup of Color Sets
Adjusting White Balance Using the Percentile and Reference Methods
We've improved how you adjust white balance in your photos!
Choose from two White balance method:
- Percentile: Auto white balance from brightest areas, good for most photos.
- Reference: Manual white balance using selected white area.
If you select the Percentile white balance method, the white balance will be adjusted automatically. If needed, move the Percentile slider to further adjust the white balance of the photo. Smaller Percentile values correspond to stronger whitening.
If you select the Reference white balance method, click or tap anywhere in the photo to choose a white point. For best results, instead of a single pixel, a small area is sampled, and the average color of that area is used as the white point.
This update gives you more control and better results when color-correcting your artwork or reference photos!
Add Margins for the Tape When Printing the Outline on Multiple Pages
If you tape the paper to the base, take the tape width (e.g., 1 cm) into account when printing the outline. You can control the tape's size with the Margin setting. The default value is 0, meaning no margin.
Color Temperature Estimation: Warm and Cool Colors
ArtistAssistApp algorithmically estimates the color temperature, whether it is warm, cool, or neutral, and shows the corresponding symbol next to the color name. You can choose a color mixing recipe based on color temperature, or create your own color set by selecting colors with the desired temperature.
Automatic Backup of Color Sets
To protect your work, ArtistAssistApp automatically exports a backup file (Color-Sets-[date_time].clrs) whenever you modify your color sets. This file is downloaded to your device's default Downloads folder, independent of browser storage.
Thanks to the auto-backup feature, you can restore all color sets with a single click of the Load color sets file button, even after unintentionally clearing the web browser storage, which results in the loss of all application data, including all your color sets.
To enable or disable automatic backup of color sets, go to the Help tab and enable or disable the Automatic backup of color sets feature.
