Every hashtag on Curate is given a color based on your personalized hashtag categories.
The number is the Post Count for that hashtag and the color indicates the post count.
Based on your follower count, Curate will automatically select the best hashtag range for your Instagram account.
You can change your hashtag post count threshold in your Account Settings accessed by clicking your profile picture in the top right while logged in.
When you are selecting hashtags to use or viewing the hashtags that you have used on a post then you will see a pie chart to indicate how many you have selected/used.
Using the pie chart you can effectively plan and monitor your hashtag usage in just a moment's glance.
