Because color blindness is linked to the X-chromosome and a recessive trait it occurs more often on men than women. So what can you do to support your husband if he is colorblind? Here are my advices:

• Choosing the right tie is a big problem; every single time. Helping out as it would be your daily business can be a relief from stress in early morning hours.
• Explaining to friends what color blindness is can be a pain in the ass. Always the same stories, the same questions, the same laughs about not so funny jokes. Let it be explained by you and give it a serious touch. This will stop their asking much faster and unburden both parts.
• Choose colors yourself and just let them be approved. Never ask a favour if there is a selection of colors included. Colorblind people never really know if it fits. They guess or learned it and don’t have the feeling for colors. And if you do it anyway be prepared for everything and accept it.
• Stop the asking-colors game if it goes on for more than just a few questions. Some people don’t know the right time to stop asking: What color do you see here? And there? – Stop it politely and remove the burden from your partner.
• Point out colorful things because colorblind people can sometimes just not spot them. They might be glowing for your eyes but not for the eyes of a colorblind. If you point it out maybe it can be seen and thus enjoyed as well by the colorblind.
• Put color into your life. Just because somebody is colorblind it usually doesn’t mean he can’t see any colors at all. If you know which colors can be seen bring them in and brush up your life of colors.

This list is of course not final but something to start with. I would be pleased to hear further suggestions from you.
