Building 'Pong' with python (codeskulptor) -
i'm trying build arcade game 'pong' in codeskulptor python. need 2 things
- increase ball velocity 10% when hits paddle
- get fix color buttons, not working
here's link code : http://www.codeskulptor.org/#user41_yjmm4nmju5x5zvk.py

for colors, color variable set pick random color list color_palette, but, other that, buttons not doing supposed to.
i'm new python , programming in general , english isn't first language please bare me.
thanks further help

you need add global color top of each of color functions assign global color instead of local color ... there many other ways solve ... require least amount of change , work
def color_red(): global color color = color_palette[0]
