I've been dabbling in watercolors for a couple of years now, and as a beginner myself at first, I totally get the worry about colors fading fast. What I learned is that looking for paints with good lightfastness ratings can make a huge difference; those are the ones that hold up against light exposure over time. For starters, it's smart to go with sets that use more permanent pigments, you know, the kind that don't shift or dull out quickly even if you're experimenting a lot.
Mixing colors sparingly helped me too, since overworking the paint can sometimes lead to uneven fading. And hey, storing your palette in a cool, dark place when not in use keeps everything vibrant longer. Works great. Once I figured that out, my pieces stayed bright for months without any issues, and it made the whole process way more fun without stressing over longevity.
Hi Hiroshi!
Moisture can block charging. If water got into the handle or around the contact area and dry it thoroughly by standing the handle upright on a towel away from the base for a day, and if you have a drying packet place it nearby to help. Do not use a hair dryer up close since heat can damage seals. Next day, clean off any film and try again. Fixed mine.
