The 2nd picture is exactly what H. malu is supposed to look like. The red color is very unusual but there is no way you could dye it to look like that. I have seen ones that were yellow or white with pink on the outside, but never that red and green combo.
The blue LTAs are pretty common, but based on the experience of others, the blue will likely no longer be visible when it regains its zooxanthellae.
Thank you for linking the actual pics, because they don't appear to be available on the website anymore.
