The poetry topic idea of the post series The Orange Series is possibly somewhat obvious: orange. Rather than looking at many aspects of orange though, one aspect will be focused on in terms of a poetry topic idea: the idea that the color orange is made of parts.
The color orange is made of the colors red and yellow. Depending on the proportions, the particular shade of orange can vary. The idea that something is made of parts, and that how those parts interact can affect the thing, can be the basis for a poem.
Some examples of ways that this idea might be translated into a poem would be things such as ingredients in a meal, people at a gathering or building materials for a project. The idea is that a poem could be written that focuses on the parts that combine to make something. In the poem, there could be a focus on the idea that how those parts interact can affect the thing.
