Closes: #529 [Model Enhancement]: Colour Detection using DL

Describe the add-ons or changes you've made 📃

i have enchanced the previous model by adding the new image loading function from keras.utils, Attention mechanism, using ELU instead of ReLU due to its better functionality, made the problem into a multi-class classification model with softmax implementation, used the optimizer Nadam with lr = 0.01, displayed the first 32 kernels based on the images, saved and included the best model as part of the PR.
