Color to B/W & Keep some Color?

Just started using PS 7 and I have a color photo that I want to convert to B/W and keep the red flowers in color. I tried selecting the flowers with the lasso and inverting but when I selected greyscale the whole pic (including selected flowers) changed to B/W. Please help! I want to create a pic with color and B/W together. Thanks!! :confused:

Do a little searching and you'll see that that question has been asked many times (recently I might add.) You'll probably get several results and ways to go about what you are doing. =)

Ok, heres what you do.
Make a selection around the part that you want to keep in color.
Now copy it, but dont paste it.
Now change your image mode to grayscale
Now change your image mode back to RGB
Now paste what you copied before, it will paste in color and the rest will still be black and white.
Wa-la
OR
you can flip the whole thing to greyscale
then flip it back to RGB
then you could make a selection around the part you want colored
then go to adjust Hue/Saturation
and click in the little box that says Colorize
then you can play with the Hue and make it whatever color you want
Hope this help!

....or, *didn't even read the post before..lol*, select with color-range, and then invert the selection, and hit CTRL+ALT+U.
