Underpainting

In the past, when I've done a painting in acrylic and ink, I've usually started with a white canvas.  A while ago, however, I decided to try painting the canvas a different colour before I started my process of drawing the picture, and then adding the finished colours.  Most of the time, I will use a blue, or green/yellow for the underpainting.  

Note:
(This is a different technique than what I do with my straight acrylic paintings.... with those I paint the entire canvas a mix of black/gesso/purple/blue... and then once that is dry, I draw my painting with chalk, and then paint it... leaving the lines showing around the colour.)

The painting I'm working on now is acrylic and ink.  I decided to try a "dulled" orange as my underpainting.  My reasoning was that I was going to put a lot of blue in the painting, and I was going to use some oranges, rusts, and reds as well.  I thought orange would be a good choice because it would complement the blue, and it would help the oranges "pop".  

For the most part, I think it is working but I find myself struggling with the orange as I am painting.  What I mean is... it is not as easy to keep focused on what I want the big tree to look like.... i keep getting distracted by the fact that it is a huge orange tree still.  So it is making me uncomfortable.    Sometimes it is hard to look past what it looks like to see what you want it to look like.  I guess I would find it easier to look past a blue, green, or even gray tree ..... the orange is just bugging me, but in a strangely, weirdly good way.  :)  The more I look at it, the more fascinated I am with it.  Hey..... i guess I kind of sound like an artist.  :)
