How can I overlay my binary gray image red?

So my current script allows me to turn a binary gray image into something that is green in the foreground (the bone) and blue in the background. However, I'd like to be able to make the bone (the foreground) red? How should I edit my code to change this color transformation from green to red?
function output = grayoverlay(img)
rgb = imread(img)
imshow(rgb);
I=rgb2gray(rgb);
figure
image(I);
hold on
image(rgb,'AlphaData', .5)

Please insert the code (NOT screenshot) in the question. To insert the code, edit, afterwards Alt+ Enter, or You can see the same icon on the upper panel in the text pad. Note: Also attach the origibal gray image.

Generally, I prefer to set this way. Before applying the color, please adjut the piels condition or area to be color
Here, just for example I choosed gray pixels greater than 120, you may odify as per your requirements.
rgb = imread(......);
imshow(rgb);
I=rgb2gray(rgb);
r_comp= I;
r_comp(I>120)=255;
%........^ Gray pixel values condition
g_comp= I;
g_comp(I>110)=0;
b_comp=I;
b_comp(I>110)=0;
result=cat(3,r_comp,g_comp,b_comp);
image(result);
