Hello,
I have a Hypercube Evolution, with an E3D V6 hotend in bowden (and the extruder is a metallic version of the CR10).
The prints i make are almost perfect (spent some time tuning the printer), but for some unknown reason every single time i try to print with a white PLA filament, the extruder skips and struggle because the hotend seems to clog.
I tried with 3 different brands, and i tried all ranges of temperatures (from 180 to 240). All the other colors i tested in pla and PETG are working just fine with the base temp.
The print starts normally, but the more it progress the more the extruder skips, and i have to cancel the print after the 3 or 4th layer because no enough/not at all filament is extruded anymore.
I change the filament to another color with the same settings (200°c) and the print goes on for hours without any skipping/clogging problem.

... maybe 240°C isn't enough?

I too have problems printing in white PLA. My white PETG is decent.
I have tried white in the following brands:
BamTack
eSun
Hatchbox
A high-end brand whose name escapes me at the moment.
In every case, every other PLA color that I tried worked great. The white blobbed, stalled, occasionally jammed, but never made a good print.
Another Reprapper I know said "its the white" that causes the problems.
I am beginning to think that he is correct.
DLC
Kits: Folgertech Kossel 2020 upgraded E3Dv6, Anet A8 upgraded E3Dv6, Tevo Tarantula enhanced parts and dual-head, TronXY X5SA Pro(E3DHemera).
Scratch: Large bed Cartesian, exchangeable heads, Linear slide Delta, Maker-Beam XL Micro Delta, 220x220CoreXY.

... not really - have some white "natural PLA" granules for injection moulding and 260°C temp rating.
Adiitives and dyes can act like "alloying material", which drastically reduce the melting point!
Had some gold-tin microspheres with 80% gold and 20% tin, which meltet the first time at around 350°C ... then the tin evaporated more and more - and the next melts needed ever more temperature, until the original gold melting temp ...
