Use Select Image Colors to specify how the image data is displayed in an image window. Images can either be displayed one wavelength at a time in pseudocolor or as one to three wavelengths simultaneously using RGB mode.
Pseudocolor shows a single wavelength in false color. The colors are shades of grey by default; you can change the palette with the "Change Lookup Table" menu in Priism's color menu. The number of colors used is typically 240 to 256, depending on the hardware. Because of the way the eye reacts to colors, you may be able to see more detail in an image when looking at it in pseudocolor mode.
RGB mode shows each wavelength as shades of red, green, blue, or a blended color (cyan = green + blue, yellow = red + green, or purple = red + blue). A maximum of 3 wavelengths can be displayed simultaneously using the simple colors red, green, and blue. If a blended color is used, a maximum of 2 wavelengths can be displayed simultaneously. The colors can only be combined so that red, green and blue are assigned once each. For example, if cyan is being used for one wavelength, the only color left to display an additional wavelength is red.
Use this option menu to toggle between pseudocolor and RGB display styles.
When the monitor is in RGB mode, you can use these option menus (one per wavelength) to select the color used to represent each wavelength.
