The source charts are provided in three formats. The charts are formatted for printing on 8.5"x11” sheets and are in the first gallery. A screen capture of the charts from Photoshop cropped down to the 2x3 aspect ratio outer box are shown here. These were captured showing the colors seen in "Proof" mode in Photoshop. This mode is intended to simulate the colors after printing in CMYK mode. Since film is also based on CMY colors, these charts may more closely match to scans from 35mm film.

CTS-3 - Screen Proof Colors

This version of the cropped image shows the colors as they were captured on-screen in Photoshop "Proof" mode for printing.

The CTS-3 frame shows a color wheel and gradients to provide a reference sample of the wider color spectrum with gradual changes between the primary colors. The source image is set in CMYK mode in the sRGB color space. The right side of the image shows primary and secondary colors as they transition to the next color in the color wheel. This chart provides an excellent target for reviewing how hue/white balance adjustments affect various colors and gradients.
