i just new to libgdx and trying to understand the example code, the following code sets the bg color


my expected color is green, R:60 Green:181 B:0, but the about code show me yellow color in my android app, anything i'm doing wrong?



glClearColor expects color values to be in 0 .. 1 range, everything outside of this range gets clamped to it. In your case numbers are getting clamped to (1, 1, 0, 0) which is indeed yellow.

Try setting glClearColor(60/255.0, 181/255.0, 0.0, 0.0); instead.
