I think this may be for @Hugo but I am not sure - but over the past few days I have received a lot of comments from staff in shops about the card colour specifically. It was mostly young women in their 20s- but they “love the colour” , “OMG! That’s so cool!” , “Where did you get that?” have all occurred.
I’m protonopic so maybe I am not seeing the big splashy colour that they are! I do have a slight problem with reading the numbers on the alpha card - and my colour blind phone helper app tells me it borders pink and peach. I think it’s the same problem I have with the red and white Santander card with white numbers. So maybe something small to bear in mind. White numbers are hard when paired w tonal reds/pinks for some people. That said you seem to have hit a sweet spot- so don’t fix what’s clearly having a positive impact!
I know design is a big part of brand and it can get lost in the drive for tech and performance. So I thought I would just share all the good buzz with you.
