The applet is designed to conveniently simulate the conversion from the RBG color represenation to the HSV color representation. The user can select the color by clicking on the cube-surface-represented RGB model. Desired color will be displayed on the second model, the HSV, represented by two lines and a circle.One line represents saturation, second line represents value. The selected color will be highlighted by small squares on both models. Also the RBG/HSV values will be shown as text next to the models. User can also find the equations used for calculations of the conversion in this applet.
