We need to know a lot more if we're going to help you. Please provide answers to the questions listed here: "FAQ: What information should I provide when asking a question on this forum?"
For a question like this, screenshots and more detail about exactly how the colors differ are important.
Are you using color management?
AE people rely on using the same terminology to keep things clear. In AE's arcane vocabulary the word "textholder" does not appear. Do you mean "text layer", perhaps?
If so, you may have caused the color change in the comp by using one of AE's Blend Modes on the layer. Or you may have an effect applied to the text layer that's causing the color change. Or if it's a 3D layer, you could have shined a colored light on it, or just the edge of a spot light is shining on the layer, effectively darkening it.
If none of those apply, you should provide more information for an accurate diagnosis.
Screenshots, system info, version info, otehr details like where you possibly obtained your template. nobody can help you based on such vague info.
