Hi FUH, I have tried over 20 plus different colours of PLA, spread across 2 suppliers, Faberdashery and Colorfabb. I have not read this anywhere but I am convinced that the pigments used to dye the filaments affect the flow characteristics.
Without doubt it is true that filaments of different colours from the same manufacturer may have different flow characteristics let alone filaments from different manufacturers. I have found that normally the difference equates to a 5 degree difference in extruder temperature from the manufacturer norm (norm being established by myself), but I have experienced 15 degrees. I am not including in this any “funny” filaments like woodfill.
Whenever I get a new filament I always run a series of tests to try and establish the optimum setting for a variety of layer depth/print speed combinations.
As for your problem of droplets, that sounds to me as if maybe you had the filament in a heated extruder not extruding for too long before starting the print and not manually extruding the filament before staring the print. Sometimes you need to extrude 50mm+ before starting. Of course it may not be that but I have experienced that myself.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
