With respect to this, it can occur in the morning or in the afternoon, but in the hours of greatest incidence it could wreak havoc on the leaves of the senecio.

Therefore, its best location may be one where it receives direct sun early or late in the day and the rest with indirect light.

Inside the house you could have it, yes, but always located as close to a window as possible to get as much light as possible; plus a few hours of direct light.

Keep in mind that the more sun it gets, the better it will be because it will make the edge of the leaves, and even the stems, a more intense color.
