I also thought of Mani Matter immediately. And I think you are selling him short. I love Lehrer's songs, but IMO Matter's lyrics even surpasses them in wit and poetical talent. His public body of work is more extensive, too. Shame really, that potentially only a few million people understand them.
I have the same issue. Not being a designer I can spend hours tweaking CSS color values, only to come back the next day and think it looks awful again. Two things have helped me: 1) using https://coolors.co/app and just trusting it, 2) creating SASS functions that derive secondary colors from a primary one. I currently don't have it at hand, but it boils down to making a series of lighter and darker versions of a given color, where, very importantly, the lighter ones are also less saturated than the shadows.
> So when we got inputs like Después de hogares crea, segunda entrada mano derecha, última casa verde (something about the last green house on the right according to Google Translate), we figured we had to validate these addresses.
Weird as it might seem, that's how addresses work in some places, if you make it invalid, you are excluding those users.
