What Cause Orange Hue On Skin?

I am a 48 yr old woman taking 150 mg of feramax iron pills a day for severe blood loss due to heavy periods. I have been on these iron supplements for over a year. In the past week, my skin has taken on an orange hue. I'm wondering if its related at all to my my large daily intake of iron, or if should be concerned about my liver not being able to process the iron, or if there is any other underlying medical problem I should be concerned about.
