DisplayPipeline.Draw2dRectangle inconsistent colors

Hi, i created a conduit that is calling Draw2dRectangle but the colors are inconsistent when i change view modes. Wireframe and shaded looks good but arctic is screwing it up (unintendedly I would say),

See attached screenshot. same method, two different view modes:

It’s drawn on my viewport like below

public class MyConduit : DisplayConduit
        {

            System.Drawing.Color[] myColors = new[]
            {
                System.Drawing.Color.FromArgb(0,0,255),
                System.Drawing.Color.FromArgb(53,0,202),
                System.Drawing.Color.FromArgb(107,0,148),
                System.Drawing.Color.FromArgb(160,0,95),
                System.Drawing.Color.FromArgb(214,0,41),
                System.Drawing.Color.FromArgb(255,12,0),
                System.Drawing.Color.FromArgb(255,66,0),
                System.Drawing.Color.FromArgb(255,119,0)

            };

            protected override void DrawForeground(DrawEventArgs e)
            {
                for (int i = 0; i < myColors.Length; i++)
                {
                    e.Display.Draw2dRectangle(new Rectangle(30, 30 + 32*i, 200, 40), Color.Black, 0, myColors[i]);
                }

            }
        }

Edit: I realized this happens only in DrawForeground and not DrawOverlay.

But still - why change the colors when there’s a RGB input? I guess it relates to baked meshes and the way their colors get altered in some views depending if vertexshading is on or off?

The faded colors might be caused by the linear workflow/display mode gamma used in rendered and arctic mode. I usually set it to 1.0 and fiddle with the shadow settings to preserve accurate analysis mesh colors and HUD legend.
