For some years there has been an interesting medium that combines drawing and painting: “Water colour pencils”.
They look like ordinary coloured pencils but the lines you draw can be diluted by water. These pencils are perfect for people who like water colour pictures, but are not prepared to walk the long way testing and practising water colours.
For example you are on holiday and you go to your special place on the beach every day. There are three palm trees, the sand and the sea and you want to do a sketch of it. But a simple pencil drawing does not catch the atmosphere, the summer feeling, of the place. Now you take a bigger sketch pad, your water colour pencils and you do a sketch with them. At home, you can dilute the lines as much as you want to. Moreover you can add some more colour to the objects by adding lots of lines and then dilute them. You are going to see that your picture looks like being done with real water colours in the end.
The advantage to real water colours: you can decide the shape of your objects by putting the lines and diluting them just the way you want.
