    You can download the Color Mod at the Biogenesis main site too (included in the main download now). You also find the sourcecode there.

Original project by Joan Queralt Molina: https://sourceforge.net/projects/biogenesis/ Includes Tyler Colemans "Features Mod": https://sourceforge.net/projects/biogenesisfeatu/ Biogenesis discussion forum: https://sourceforge.net/p/biogenesis/discussion/ Biogenesis runs faster (at least for myself) if you open a Google Chrome window (don´t know why :D)
