Get banks to have credit/debit cards options for people with colour vision deficiency

There are over 320 million people worldwide who suffer from a form of colour blindness, mostly males (8% of the population). Having dealt recently with HSBC bank, they do not seem to be up to date with how to deal with people with this form of disability. We need to change their attitude. They have redesigned their cards to all be similar across 30 countries but with different colour combinations. I have been told on the telephone that the grey business debit card I have will not or cannot be replaced with any other colour. The card to me is silver with a shiny silver lion and silver embossed numbers making it impossible to read (like the image above but imagine it being laminated, shiny). Many people have already said they have cards with such issues and they are not colour blind so this needs to be addressed by all banks.
