Color

MixingColor – Compare how colors mix using pigments and light
TriColor – Explore the colors created by mixing varying intensities of red, green, and blue light
GameTriColor – Test your ability to identify the intensities of the red, green, and blue components of a color on the computer screen.
ReportTriColor – Measure how well you can identify the intensities or red, green, and blue for 10 random colors

Digital Images

PixelView – Study the effects of changing the size of pixels for any digital picture
ColorPicture – Separate the red, green, and blue color components of any digital picture
LeafAnalysis – Similar to ColorPicture but designed for science centers
SplitColors – More advanced manipulation of the red, green, and blue color components of any digital picture
FalseColor – Similar to ColorPicture, manipulate the color display components of a Landsat image from USGS Earthshots
SurfaceType – Use simplified tools to analyze the spatial and spectral information within a Landsat image from USGS Earthshots
SurfaceTypeRGB – Use simplified tools to analyze the spatial and spectral information any digital image. Very useful to examining digital photos from the International Space Station (EarthKAM). 
ForestAnalysis – Simultaneously interact with maps of old growth forests for the United States from 1620, 1850, 1926, and 1990

Image Analysis

LandsatAnalysis – Use more advanced tools to analyze the spatial and spectral information within a Landsat image from USGS Earthshots
VegetationAnalysis – Use more advanced tools to study the spatial and spectral information within a time series of Landsat images from USGS Earthshots
MVHimage – Use more advanced tools to analyze the spatial and color information within any digital image (jpeg, gif, tiff, png, pict, pdf) - digital photos, color-coded maps, orthophotographs, satellite images

Utilities

MergePictures – Utility to combine sequence of time lapse images into one image
SatImageMaker – Utility, when combined with ColorPicture, that makes Landsat color composite from visible and infrared photos
ColorScale – Explore the utility of different color scales using combinations of red, green, and blue
FilterCombo – Calculate the spectrum of light passing through a combination of filters available for theater lighting (Rosco, Lee, Apollo, etc.)
