View source for IPhone change calendar colors

sqlite3 should be installed by Cydia, or from command prompt:
 apt-get install sqlite3

Query your current config:
 cd /var/mobile/Library/Calendar
 sqlite3 Calendar.sqlitedb
On the sqlite prompt:
 select store_id,title, external_id_tag,color_r,color_g,color_b from Calendar;

In my case the output is:
 1|Default||-1|-1|-1
 2|Birthdays||47|141|0
 1|Calendar||15|77|140
 6|Calendar||15|77|140
 11|Tasks|/dav/roland@breedveld.net/Tasks/|245|120|2
 11|Calendar|/dav/roland@breedveld.net/Calendar/|132|130|132

Change the colors, on the sqlite prompt:
 update Calendar set color_r=15, color_g=77, color_b=140 where store_id = '6';
 update Calendar set color_r=181, color_g=0, color_b=13 where store_id = '11';
 .
 .exit

Colors should be effective immediatley<br>
