The color of the notes is different for different skins, so just calling them by colors is a bad idea. Instead you should refer to them by the number of the column they're no. in 7k it would be 1 2 3 4 5 6 7 with 4 being the middle key (usually space bar). When I write down patterns, if the patterns are just single notes, I write them like 2461357 with 1 number for each note. This pattern would be the left hand middle key, then the middle key/space bar, then the right hand middle key, then left hand first key, third key, left hand first key, then third key. If the pattern is chords (multiple notes at once) I write them like this: 246/1357. The slash separates chords.
The patterns you showed there would be 25 and 36.
You're still in the early stage of learning to play mania. This means you haven't learned how the play those chords yet. I'd suggest actually focusing on playing maps that have those chords more often. I don't mean grinding plays on them, just forcing yourself to play them a bit more often than you do right now. Eventually your brain will figure out how to hit them and you can move on to other patterns you have trouble with.
Since mania requires a few different kinds of skills, one of those skills is the ability to recognize a pattern and hit it correctly. In the beginning, simple patterns like this will cause you trouble. Once you get better, you might be able to hit those chords properly, but if they have a few of those in a row, you might still have trouble hitting them. In this stage of learning the thing you want to do is find as many of those tricky chords or patterns and practice them. Eventually you'll notice that there aren't very many kinds of patterns you have trouble with, but the ones you do find hard will be very hard to learn. That's when you know you've got past the early stages of learning and now you're at the point where most of the basic skills are developed.
The thing about mania is that your learning is never over. There will always be something you can't play.
