Well I always thought it meant scaled since it works for gray scale and I don't use the word "color" for gray levels. And it is consistent with the sc in soundsc() vs sound() function where it means scaled (since sounds don't have visible colors).
However the help says this:
imagesc
Display image with scaled colors
imagesc(C) displays the data in array C as an image that uses the full range of colors in the colormap. Each element of C specifies the color for one pixel of the image.
So I guess it's somewhat ambiguous whether the c is from "scaled", or if it's from "colors".
