NOTE:
Somehow provider.excute() function is so snsitive about the params order we passes, and when I pass the defaultParams incorrect order, it parse the color to 0, and inside contract, fade() called instead of pu_color(), that's why we cannot paint any pixels by newer systems calls but now fixed. and please be carefull about params order
