Customize your color at 1
When done, tap at 2
Tap 3 to add the color to your palette. This color should be available next time. (Remember to tap at 2. This is where your custom colors are stored.)
As far as "web safe" colors go, the easiest thing to do is to use the icon between 1 and 2 and specify RGB and input the values associated with web safe colors. You can then build a palette using the above method. (TIP: To get rid of colors in a palette, simply flick them off.)
Thank you so much!
Very kind and thoroughly helpful, really appreciate it.
I can only apologise if that info was to hand somewhere in the program, but I am yet to find it.
It's all good. There is a lot to cover so it can be daunting. The best tip I give is to, "learn by doing." e.g. If you have some free time, take an image and experiment or just futz with the various tools to see what they do. There's the tutorials inside the app itself as well as some videos by Adobe themselves.
