GUI.DrawTexture & GUI.Label color do not match visually, even though same value

Hi!

I am trying to draw some text over a drawn texture in the scene view. I generate a texture with a given color, which I draw in the Scene View using GUI.DrawTexture. I then render text on screen using GUI.Label, for which I create a GUIStyle for which I set its normal.textColor to that same color. Yet these colors do not match visually.
It seems that the textcolor has some offset which causes the color to shift a little.

This is the code I use to do this:

        //Calculate 2d position on screen from 3d position
        float sceneViewControlBarHeight = 21f;
        Vector2 screenPosition = SceneView.currentDrawingSceneView.camera.WorldToScreenPoint(_component.transform.position);
        Vector2 invertedScreenPosition = new Vector2(screenPosition.x, (-screenPosition.y + SceneView.lastActiveSceneView.position.height - sceneViewControlBarHeight));

        //Create GUIStyle
        GUIStyle style = new GUIStyle(GUI.skin.label);
        style.normal.textColor = _component.TextColor;
        style.fontSize = 48;

        //Create image Rect
        Rect imageRect = new Rect(invertedScreenPosition.x, invertedScreenPosition.y, 265, 90);

        //Draw background, border, icon and label
        Handles.BeginGUI();
        GUI.DrawTexture(imageRect, _component.BackgroundTexture, ScaleMode.StretchToFill, true, 0f, _component.BackgroundColor, 0f, 30);
        GUI.DrawTexture(imageRect, _component.BorderTexture, ScaleMode.StretchToFill, true, 0f, _component.TextColor, 10, 30);
        GUI.Label(imageRect, "Some Label", style);
        Handles.EndGUI();

And here is what it looks like:

Although this effect does not show equally for all colors, as seen here:

Can somebody tell me why this effect occurs, and how I might be able to fix it?

Thank you!

SOLVED (sorta):
During reviewing I the post once more after posting, I realized my own mistake. By setting the color in the GUI.DrawTexture, I created that offset. By setting those color to Color.White, both colors are now offset. They are now both not exactly the color that has been set, but at least the are equal now. That fixes my problem for now, even though I still do not know why the offset in color is there…
