First, pardon me if my english isnt correct ( i am french )
I am beginning to paint with oils but i am having some problems with it.
the fact that the colors dont dry fast is interessant to mix my colors and make nice ranges of colors but there is a problem : when i want to put a color on another one, they mix together. Especially when i put a light color on a dark one. but in certain case i dont want these colors to mix ( with highlights for example or to replace a color by another one ).
So do i have to wait till the paint is dry ??? But how do the plein air painters to achieve such highlights or color replacements ( knowing that they just have a few hours to achieve their painting) ?
Another problem is that when i paint on a canvas , my painting dries very slowly ( in about 5 days ). I bought a quick drying medium but the drying remained almost the same.
but when i paint on cardboard or a simple paper it dries extremely fast ( too fast ) ( in about 15 minutes ).
I much prefer the feeling when i paint on a canvas but what do i have to do so that my paint dries a bit faster ( a few hours would be great ) ?
Sorry for the length of this text but if you could answer it would be great for me.
