@Ragini Gaikwad, this is not a comment for @shima said on regarding his 8 year old question on CBIR. This is a new question, so please start your own thread.

Just try taking the mean of each color channel and have that be your feature vector that you save along with each image's record in your data base.
% Extract the individual red, green, and blue color channels.
redChannel = rgbImage(:, :, 1);
greenChannel = rgbImage(:, :, 2);
blueChannel = rgbImage(:, :, 3);
% Get means.
meanRed = mean2(redChannel);
meanGreen = mean2(greenChannel);
meanBlue = mean2(blueChannel);
Then, for a desired color that you want to find in your database, search all records in the database for those whose mean colors are close enough to your desired color and return them.

The square root of the sum of the squares of the distances:
euclideanDistances = sqrt(sum((featureVector1 - featureVector2))^2));
or something like that.
