Colorwise is an iOS color sampler. Colorwise can sample colors straight from the camera or from an image. The sampled color is displayed along with the color components converted into a variety of formats including RGB, HSB, CMYK, CMY, Lab, hLab and XYZ. Libraries of colors can also be used to assign colors appropriate names. Sampled colors are stored in a list of swatches that can be exported in a variety of formats including Adobe Swatch Exchange (ASE) format that can be used in popular design programs such as Adobe Photoshop, Adobe Color File (ACO) format as used by Adobe Photoshop, Adobe Color Book (ACB) format as used by Adobe Photoshop color libraries. Additional formats include a simple text format that can be edited from Colorwise and CSV (comma separated value) format which can be used in spreadsheet applications such as Numbers and Excel. An HTML page can be generated showing the colors and color values. Colorwise can also import ASE, ACO, ACB, Text and CSV files. This makes it possible to import colors from Photoshop and other graphic software. Color libraries can be exported to the iTunes documents folder emailed, sent in messages, uploaded to iCloud Drive, Google Drive, Dropbox, shared with AirDrop and sent to other apps. Use color libraries to match colors sampled by Colorwise. When a color is sampled, the closest color match in the library is used to provide the color with a name. Included are eight color libraries with over 4500 named colors. A color picker is provided similar to those in popular color programs to create color swatches or modify colors. To demonstrate the effect of color on the human eye two complimentary visual effects are included.
