Accent colour

I remember a tutor comment about choosing colours for a piece. He wrote that he would like to hear how I will work with an accent colour in future.

What is an accent colour:

I tried according to rule "most, some and a bit" some pieces:

I tried watercolour and some pastel. Just to play with yellow, blue and red as an accent colour. Not so satisfied with the first drawing but I need to try more. One of them was inspired by MIRO painting.

When playing I realized, that there must be taken the background on the mind, the white is one colour as well :-).

I came back to Photoshop after the small trial to draw by hand. I do not want to give up to use colour in hand drawing but I need some skills. I made a simple piece. I used the wheel colour and choose the colour in a triad and monochromatic palette. I made a yellow background on it I put some dirties because it looks better than just monotone colour. As a next step, I added some colour by splash brushes. The final step was to put a bit of red colour. The result looks better than my hand drawing trials. I need to think where is the difference, It looks more compact, it is not childish appearance, the splash has a good shape. I need to improve my hand drawing for sure.
