TIP 1) the right click trick

left and right mouse click correspond to col1 and col2 respectively, which u can see in the top bar. this applies to all brushes and the fill tool like above. when using shapes col2 will be the fill colour (if you have solid fill selected). right clicking with shape maker will reverse the colours use on the shape.

TIP 2) right click eraser

this one is extremely helpful for lineart or add shading. the eraser always uses col2. so your eraser can technically be any colour. but here's where you get powers: right clicking with eraser will only erase onto col1, with col2.

TIP 3) transparent selection change a guy destination

the beloved transparent selection tool works based on what is selected as col2. so long as you have the correct colour as col2 you can make any image transparent and put it on top of anything else. and yes this works with photo bg as you can see.

TIP 4) the gradience

this one is a little more complex. you want to start off with any canvas size, and make as many diagonal coloured bands as you want. (protip: holding down shift makes a perfectly diagonal line with line tool)

then you need to resize the canvas to a width of 1px (make sure you resize by pixels, and do not maintain aspect ratio). then resize again back to its original width (or a different width i cant stop you). you will have your lovely gradience.

TIP 5) superimposter

so. you got a cool gradient and wanna put a guy on it. heres what i do:

i open a 2nd mspaint with same canvas size and draw whatever i want on there. i then pick a completely unrelated colour to my entire piece, and set that as the bg. you could use white, pink, geen, whatever you want as long as it doesnt appear somewhere else in ur drawing. copy the guy.

go back to your gradient tab. ensure that col2 is set as that bg colour you picked (lilac for me). have "transparent selection" enabled. paste your guy in. cue fanfare

TIP 6) advanced superimposter

the great thing about this method is u can put multiple gradients in multiple areas of the image. this is where it gets all japanese printmaking type of shit. ukiyo-esque

all you need to do is make another canvas with a new gradient, ensure col2 is set as the colour you want to replace, then paste your original piece onto the new gradient. now my guy has a soft fade. you can do this as much as you want. (you could even make a canvas with a texture or photo and paste your drawing onto there)

TIP 7) "sketch layer"

so as you now know, col2 is what is removed when you click "transparent selection". which means you can also remove any instance of a colour from ur drawing. which means you can have a unique colour for sketch layer and remove it from the drawing later. i admittedly dont do this but it is a great trick to have.

now combine this with lowering your dpi for smoother lines. may seem obvious but it helps. its like a free stabiliser whenever u want.

TIP 8) rainbow art

now this is where you can get dizzee rascal "bonkers". check out my small and shitty rainbow trick. you can select anything and hold down shift, then drag with left mouse, to turn that selection into its own brush. i even did it with a guy. and you can of course do this with a photo as well.
