RAMA Save Pixels node

I want to get all pixels from a picture then change the RBG for each to new percentages (70% red 5% greed 20% blue) then save the result as new picture. But the only node that i can connect the array input of the Victory Save Pixels node and make it work is the load node. This will not actually allow me to do any changes with the pixels. How can I do it? I even connected it to make array node and gave it colors from color vaiable but the result is 2x2 white pixels only

p.s. i will need to create custom picture at least 100x100 pixels and i dont want to make 10000 nodes doe this. I need an algorithm from load pixels that changes the color of each then export the result
