Final cut transitions

Dear Tom, I didn't succeed in creating the transitions following the steps you indicated. I want to thank you for steering me in the right direction. It turns out that when I try the last step, I got a legend saying there was not enough space between frames to accommodate the transitions. I could create transitions creating more space between frames and by experimenting with the I realized is nod fading but cross-disolves what works in my project. Again, thank you very much. Carlos de Hoyos.

Thank you Tom for your input, however in Transitions I can't find the "fade to color" option". I only see disolves as an option.

Any other suggestion for how to access "Fade to color"?

This is what I have: I searche fade to color at the bottom.
