Set lighter shades of Ascent colors of theme to a shape in Aspose Slides

Hi There,

We have a requirement where we need to set lighter shades of the Ascent colors of Theme to some shapes and maintain the theme. i can set the Ascent color, but how do i manipulate the color such that , the color lighter than Ascent color should be applied.
Below example:
AutoShape shape = ((AutoShape)pres.Slides[0].Shapes.AddAutoShape(ShapeType.Rectangle, 0, 0, 100, 100));
shape.Name = “shape1”;
shape.FillFormat.FillType = FillType.Solid ;
shape.FillFormat.SolidFillColor.Color = pres.MasterTheme.AsITheme.ColorScheme.Accent1.Color;// Here I want one shade lighter to Accent Color.

How can we achieve this? Any example around this will be helpful.

Best Regards,
