[Genome] custom coloring a bedGraph track?

[Ginger Cheng]

Hello, Browser Gurus,

Just wondering if there is any quick way to color a bedGraph track based 
on a field of the data table. So it would be sth like

chrom | chromStart | chromEnd | dataValue | color

| chr1  |   16190712 | 16190763 |    -0.548   | red
| chr1  |   16190782 | 16190803 |    -0.001   | gray


THank you for any help in advance
