This is the page with the interesting chart made by the user szilard. I'm sure everyone can find something wrong with it, but I think it'd be useful to use. It's not as clear as janMato's invensions, but he seems to have a gift of making clear expressions. Well, here's the chart (I'm hotlinking it now, so if that's a problem just send me a message).
jan-ante then suggested an interesting way to use them practically for taste:
pilin uta walo - salty taste (salt)
pilin uta jelo - sour taste (lemon)
pilin uta loje - spicy taste (pepper)
pilin uta laso - mint taste (should be green, but...)
pilin uta pimeja - bitter taste
