NEWBIE..how to isolate & change a color?

[lou4uandme]

Hi all,
My first post!
I came from After effects , combustion & Toxik and now NUKE. The one thing that I can’t seem to find, is a way to Change a isolated color.
For example, To change a red shirt to blue. In the other apps, this was very easy. I found the nodes HUE CORRECT & HUE SHIFT. These can Isolate a color and I could play with Saturation & Luminance but I can’t seem to “Change” that specific color.
Can anyone help me?
Thanks,
Lou

Check the HSVTool.

Really crude example:

Constant {
inputs 0
channels rgb
color 0.225
name Constant1
selected true
xpos -393
ypos -151
}
Bezier {
points {{
{484 658 0 -2.25}
{576 540 0 -0.25}
{734 594 0 -1.17}
{722 192 0 -0.79}
{1160 166 0 0.88}
{1070 610 0 1.36}
{1244 558 0 0.24}
{1320 672 0 2.21}
{1046 822 0 3.01}
{908 726 56.7 -3.05 56.7}
{786 798 0 -3.02}
}}
shape {{curve i L x1 0}}
center {960 540}
color {1 0.0727987 0.0513617 1}
name Bezier1
selected true
xpos -393
ypos -76
}
HSVTool {
srccolor {1 0.073 0.051}
dstcolor {0 0 1}
huesrcs {1.39094 1.39094}
huerotation 238.609
huerolloffrange 50
satsrcs {0.949 0.949}

I am REALLYYYYYY new to nuke. These lines of code , i’m guessing can be inserted into a node or script? I have NO idea what to do with it.:confused: Can you give me a hint?
Thanks so much,
