You can use any colors and/or combination of colors. (ie. use 1 color and finish with "Decorate" go back then use same options except a different color)
Any Composite Effect(s) and/or combination of Composite Effects.
(ie. use 1 Composite Effect and finish with "Decorate" go back then use same options except a different Composite Effect) You can use Border, finish with "Decorate" go back then use Frame,
or use Frame finish with "Decorate" go back then use Border,
use Border both times (as long as there is at least one other variable ie. 2 DIFFERENT COLORS) ,
use Frames both times (same rule of thumb as both Borders IE. 2 DIFFERENT COMPOSITE EFFECTS)
OR For those XXXTREMELY ADVENTUROUS You can use "DECORATE COMPOSITE" more than twice,,, 3, 4, 5 times if you wish. (ie. 2 different colors, 2 different Composite Effects,etc)
***Each time you take an image through Decorate and use Decorate/Composite than output out of Decorate that is referred to as ONE CYCLE of Decorate Composite
Given the number of varibles, the possibilities are endless.
However, not always guaranteed a "winner", You have to try until you come up with a successful image. The real trick is in picking the right color or combination of colors. HAVE FUN!!
