HnH has only 15 colors to use on sketches and devs really take their time on adding rest of the few million!
Have you ever tried to upload nice, colored sketches, only for them to turn out like this?
Want to make them look like this?
But are you too lazy to make them better by yourself?
Fear not!
I have made a site which will do the conversion for you automatically!
Original
HnH default conversion
My site
Basically, it will use those 9 HnH sketch colors kind of like a computer monitor uses RGB-lights, or like a printer uses few colors, creating an illusion of many different colors when you look from far enough distance.
How to use
1. Go to the site, upload any image (jpg, png preferred, may not work with others)
2. Wait
3. Soon image appears on the right hand side, save it and upload to sketch.
