Thanks a lot @Damzini for reporting this 
We pass all our designs by Color Oracle but there aren’t many silver bullets to this kind of questions 
To be honest, we still have a long way towards accessibility, we use very small fonts in some places and sometimes contrast is not good enough either. Good thing is that all this is on our list and we’ll sort it out at some point, I’m just sorry it’s going to take us a bit of time and polishing, please bear with us
