In the compound [Cu(NCCH3)]+ BF4 , Copper is in +1 oxidation state.

Copper in (1) oxidation state compounds are colourless or usually white.

Hence this will be a colourless compound.

The elemental copper's electron configuration is [Ar] d₁₀S₁.

S₁ means it's d - shell is completely filled.

d electrons of transition metals give them their color.

Since d₁₀ complex has no where for electrons to be excited because it is completely filled, all the light wavelengths are reflected giving a white compound.
