Processing uses the keyword "color" as an "int".

You can see the replacement in the .java files created by Processing.

Yes, that's part of the "magic" (pre-processing) that the PDE does behind the scene... You won't be able to write fill(#BADCAF) not int(floatVar) in Eclipse for example, because Processing changes that on the fly.

is that mean coding using eclispe is different  ?

so what is i hv to set the color white ?
background(255) in eclipse would result a blue one  not white

i sw in a example they hv used background(0xffffff) but its not simple
is there a function to convert from number values to color values ?



i like eclipse becos it gives ALL the available functions after i put a "dot" Smiley .very easy becos i dont hv to remember the names of the functions

if the processing IDE gv the same functionally no one would hesitage to use that for developing.

A 'color' is an 'int'.
You can simply use "int c = color(255);" instead of "color c = color(255);"

If you export from the PDE, you can see what processing turns a 'color' into by opening the .java file it creates.
