Java Colors

If you want to play with some colors to put into your html document you can do that here and get the color code you need for the document. Also, for many documents you can click on customize colors and find out the numeric codes for red, blue, and green in an image that is in edit mode. You can plug those codes in here to get the html equivalent code. This is very handy when you are trying to match colors in an image with a border in an html document. This was the first java applet that I ever made myself. I have learned other programming languages since then and done most of my work in other languages. I'm not sure whether or not I am going to come back to programming in Java.

Below are some examples in a web page. The colors may look slightly different than they did in the applet above.

red=0, green=0, blue=0, html code= #000000 red=127, green=127, blue=127, html code = #7F7F7F
red=255, green=255, blue=255, html code= #FFFFFF red=255, green=0, blue=0, html code = #FF0000
red=0, green=255, blue=0, html code = #00FF00 red=0, green=0, blue=255, html code = #0000FF
red=255, green=255, blue=0, html code = #FFFF00 red=255, green=0, blue=255, html code = #FF00FF
red=0, green=255, blue=255, html code = #00FFFF red=100, green=100, blue=255, html code = #6464FF
red=200, green=100, blue=0, html code = #C86400 red=180, green=40, blue=100, html code = #B42864
red=75, green=100, blue=75, html code = #4B644B red=170, green=60, blue=25, html code = #AA3C19
