What are the colors of your TLC-spots to the naked eye?

When working with conjugated small molecules, you could be able to identify the structure with the longest conjugation (i.e. the largest molecule) just by their color on TLC-plate.

I have synthesized a very similar compound, and that looked orange to the naked eye on TLC-plate. I bet yours does too.
Yes, I also see some colored spot with the naked eye. Where is your product position on TLC plate, is it in the middle of two starting materials or on the top?

On the top. My eluent composition was toluene : n-hexane on 1:1 ratio by volume, and the product was the first to elute.
Do you use Suzuki reaction or Stille coupling?
