The color the indicator needs to be depends on what it was when the desiccant was fresh. If the indicator color was blue, then it will turn pink when saturated with moisture. If the indicator was orange, then it will turn green as it absorbs moisture. So, the desiccant cartridge will need to be replaced if the indicator is either pink or green.
FYI: The desiccant indicators that turn blue to pink contain cobalt chloride, which is toxic. The orange to green alternative is non-toxic. Source: http:www.silicagelpackets.com

It should close smoothly without any force required, if you find its not closing properly then check that the cartridge is sitting in right.
One method would be to weigh a desiccant and then expose it to your known target volume to allow it to dry the material. Then re-weigh the desiccant. If your'e looking at a low % of water vapour, you should attempt to minimise the 'tare weight' of your desiccant. Crumbled calcium sulphate is a safe desiccant - just dry it out well beforehand.
