You're correct. Purple is lepidolite and the green is the spodumene. The crystalline texture plus the colour tells you that - multiple criteria are required for positive mineral identification. The spodumene is coarse-grained blocky crystals, the lepidolite is the fine-grained irregular mass. In pegmatites, 99 times out of 100, purple will mean lepidolite although not all lepidolite is purple. The 1 out of 100 times will be where you could get purple-coloured spodumene, referred to as kunzite in the gem community, but I wouldn't expect to see this outside of Brazil or the Afghanistan region.

You can see the blocky light green spodumene with the irregular patches of fine-grained lepidolite, with the dark grey quartz intergrown between the spodumene.
