i started with the grid background and wrote "hi" in white and then for every frame i did this: i went to the color picker menu and under the shade thing (the black to white bar thing) there's "lum" (luminosity) and 240 is white and 0 is black i started at 240 and for every frame i used the tool that only writes over other markings and put the "lum" down 10 points every frame and then i went through and (SLOWLY bc itll ruin it if you go fast you gotta pause before doing the next frame) and put white on the background
