The colored circle you see when catching Pokemon changes if different ball types are used, but doesn't change when you use a razzberry. So there doesn't seem to be consistency whether it changes based on anything besides Pokemon level, but has anyone determined whether the catch bonus changes the color at all?

    As far as I know, it changes with Razz Berry. The change is just much smaller than when you change Balls, so it's not really noticeable.

    @scenia pretty sure razzberry and Greatball have the same catch boost (50%), but berries change the color far less noticeably than Greatballs, if at all

This can help you, it calculates the catch chance with color circles and on the bottom of the page explains you a little about how they do the calc.


Extra info from link [13/10/2016]:

This tool allows trainers to view catch chances of different Pokemon based on the ball they use and the colour of the ring they observe in-game.

The colour of the rings in this tool match exactly the colours in game thanks to some stunning research by u/dondon151 (reddit user).

Ring size calculation is still tentative but accurate to a reasonably large sample size thanks to a lot of work by u/RhyniD (reddit user).

The science on catch chance isn't 100% complete, but for what we know right now, this tool is accurate:

Final Chance = 1 - (( 1 - Level Chance) ^ BallMulti) ^ SizeMulti


Level Chance = 50% / CPMulti(Level) * Base Species Chance

The SizeMulti increase from 1 to 2 as the coloured ring's size decreases relative to the grey ring.

The BallMulti increases from 1 -> 1.5 -> 2 as the trainer uses better balls.

There is no evidence yet that Berries, "Nice Throws" or curve balls affect catch chance.

The research add information about 'Great, Nice & Excellents shots' multipliers and Berries, not included on pokeassistant.

  • Second: The information on the guide is incorrect (outdated). Great, Nice & Excellents shots give a boost on your capture chances.

  • ok thanks, any demonstration over there about the 'Great, Nice & Excellents shots' boost? @SysDragon Oct 13 '16 at 7:56
