Neither, maybe both.

Don't rely on the colours.

Measure the resistance from each wire back to the plug to be sure.

ok, so conclusion that i can get is white is D-.thanks :)

As other have tried to tell you NEVER trust a wire color to remain consistent from cable to cable, even if the 'standard' list a color code... Trust me you will get burned and find out the hard way that manufactures rarely follow a set color code on fixed end cables... Manufactures will use what they have on hand, if they have a 4 conductor wire that is red, orange, green and black that they use for whatever and it will work for their USB cables they will likely use it vs sourcing the proper red, green, black and white cable... And even if they do use the right colored cables, there is no guarantee that they used it properly...

Always do a continuity test to the plug and verify what wire goes where...

but the sequence is like this right ?

Pin 1 VCC
Pin 2 D-
Pin 3 D+
Pin 4 GND

Hi,
Don't trust colors. I have got an usb cable with black is Vcc and green is Gnd. What we need to do is to measure with DMM.

Check it with a multimeter!

Also you can use a led with a resistor 200Ohms for check it!

Ignore Rodrilyx. His first comment was OK, but the rest are questionable.

Determine what are D+ and D- by using your multimeter on the Ohms range to test what pin the wires are connected to.

You should do that for all 4 connections.

Then you can verify by ensuring that +5V appears across the Vcc/Gnd pins.
