JColorChanger (formerly Color Changer) 1.0
A lightweight Java-based application that enables you to view a color based on its RGBA parameters and easily generate lighter and darker hues
The program allows you to change the RGBA values and obtain new colors, thus helping you understand a color's composition. You can change the RGBA parameters by sliding the arrows on the bars, or typing in a value between 0-255.
Once you have the color you desire, you can choose to darken it, lighten it or even view it in grey scale mode. The program also allows you to apply warm or cool filters to the selected color.
