Virtually all of these sunsets would have been boring if shot in color. It sounds stupid to say it but the trick is not to look at the color.
Look at the sunbeam shining off the water. Look at the silhouettes. Throw on a red filter to highlight the clouds.
Forget color. Any idiot can use his iPhone to snap a picture of a colorful sunset. It takes a master like you to turn that sunset into a work of art.
Sunset is all about the time when day turns into night... When light turns into dark.
It just so happens that you have the perfect medium for capturing the difference between light and dark: Black and white film!
B&W images of sunsets require atmosphere, such as clouds, storms, bursts/shafts of light or contextual/complimentary subject inclusions. It is no good at all for straight on sunsets that could otherwise be exploited to their full potential in colour, particularly E6 film.
Only two of the B&W sunset posts preceding this actually provoke a response in me (top left, bottom right). The other two are too pedestrian.
Try sunsets in color on different formats, at different EI ratings and viewpoints. It is useful to thoroughly scout a location beforehand to exclude people, footprints, fences and flags.

The late Barry Thornton took a great B/W sunset - I think it is in his book 'elements'
Also Dave Chamberlin in his book "The Creative Monochrome Image".
I always reckon colour photography is much easier than black and white. With only shades of grey you really need good composition and imagery - you can't dazzle with daglow.
So... maybe see it as a challenge?
Respectfully, I think the opposite is true. You only need to look at how many people convert shots to B&W, and apply "film grit" effects to see that for many people B&W = Art, and therefore any photo looks better in B&W. Also B&W hides exposure mistakes better, and just generally looks more like "proper photography" to a lot of people.
But back to the OP's question, I think it's worth at least trying some colour, there are some lovely BW nature shots in this thread, but I do think that nature has the ultimate colour palette, and it's a shame not to use it.
