@Image Analyst
function pxds= pixellabeldatastore()
pxDir = fullfile('D:\master\thesis\pilot study\roads_colors');
classes = ["biling" "car" "pedestrian" "Road" "Sky" "greens" "pole" "Pavement"];
labelIDs={
% "Builing"
'(237 252 0; % "Builing")';
% "car"
'(169 0 189; % "car")';

Using a folder of example images that ships with MATLAB, I was able to run your code in R2021a once I updated the labelIDs to be an array of numbers.
classes = ["biling" "car" "pedestrian" "Road" "Sky" "greens" "pole" "Pavement"];
labelIDs=[237 252 0;
169 0 189;
252 0 0;
77 77 77;
0 45 172;
92 155 3;
119 127 3;
255 128 5];
pxDir = fullfile(matlabroot,'toolbox/vision/visiondata/stopSignImages');
pxds= pixelLabelDatastore(pxDir,classes,labelIDs)
pxds =
PixelLabelDatastore with properties: Files: {41×1 cell} ClassNames: {8×1 cell} ReadSize: 1 ReadFcn: @readDatastoreImage AlternateFileSystemRoots: {}
