-At this moment there is only one funcion, `gradientX`, which allows to create gradients between two colors:
+These are functions to make gradients with the specified colors.
 
-`gradientX(r0=1,g0=0,b0=,r1=0,g1=0,b1=1,speed=0)`
+Use `gradient2` to create a gradient between two colors:
+
+`gradient2(r0=1,g0=0,b0=,r1=0,g1=0,b1=1,speed=0)`
 
 Examples:
 
-`gradientX(1,0,0,0.8,0,0.8,0).out()` creates a gradient from red to purple.
+`gradient2(1,0,0,0.8,0,0.8,0).out()` creates a gradient from red to purple.
+
+`gradient2(1,0,0,0.8,0,0.8,2).out()` the same gradient, but now animated.
+
+`gradient2(1,0,0,1,0,1,2).scale(0.4).kaleid(100).out()`.
+
+Use `gradient3` to create a gradient involving three colors:
+
+`gradient3(r0=1,g0=0,b0=,r1=0,g1=0,b1=1,r2=0,g2=1,b2=0,speed=0)`
+
+Examples:
 
-`gradientX(1,0,0,0.8,0,0.8,2).out()` the same gradient, but now animated.
+`gradient3(1,0,1,0,1,0,0,0,1,0).out()`
 
-`gradientX(1,0,0,1,0,1,2).scale(0.4).kaleid(100).out()`.
+`gradient3(0.8,0,1,0.7,0.7,0,1,0,0,0.2).scale(0.2).out()`
 
----
+`gradient3(0.8,0,1,0.7,0.7,0,1,0,0,0.2).scale(0.2)
+  .blend(gradient2(0,0.6,0,0.7,0,0.3,-0.4)).out()`
