It may be fine to you. It's still not fine to me. The other pickers have icons to indicate what they are (calendar and clock) so why not a color palette to provide a similar hint? Needing to read the context to figure out if it's a button or a text field does not help when quickly scanning the page. Figuring out the context and reading the labels is totally unnecessary extra work that a better design wouldn't require.
