background and word logo the same color and can see text

ajkiamc,

From the wording "background and word logo the same color", the answer can only be what Peter said, namely to have something lighter to separate them, and that something will then be what shapes the logo and makes it visible.

The additional approach where either is darker and the other is paler, that Peter mentions and shows in the second sample, is strictly against the wording.

But both ways, and especially the latter, can be seen/perceived as a representation of the real world experience that the same black can appear differently depending on reflection of light by different surface properties, especially the contrasts between lustrous and lustreless where the former can also have highlights; this could be built into the logo, a bit like what we can see on the Adobe 17 oz Stealth Mug which actually has the exact same black colur throughout.

For accessibility, this is not a very good idea.

I don't know if this is remotely what you're after, but it seems to me that there has to be something lighter to separate the letters from the background, or the letters themselves must be a sufficiently different black to make them legible

The top one is a lighter fill behind the black letters with a path offset and feather effect applied; second one is lettering in dark gray rather than black; third is a stroke with a gradient from 100% white to 0% white.
