they try to get as much color accuracy as possible, but with a lot of HG kits, some colors will still be missing so you either have to use stickers or paint
the more advanced kits like RGs and MGs will have better color separation and will be more color accurate out of the box than HGs
but people still like paint their kits despite this
modern Gunpla doesn't need any glue
